->''"A 10% chance is pretty unlikely, but everyone knows that a one-in-a-million chance is a sure thing!"''
-->-- '''Elan''', ''Webcomic/TheOrderOfTheStick''
%%One quote per page only, please

In layman's terms: ''if there's a million to one chance against something of vital importance happening, then it's that one time rather than the other nine-hundred-and-ninety-nine-thousand-nine-hundred-and-ninety-nine times''. This is TruthInTelevision in a sense, that if an extremely improbable event occurs to someone, chances are that it's [[AnthropicPrinciple his story that's told]]. What the trope hinges on is the reality that each audience member is an individual, and, thus, their own "number one": undeniably, each audience member is one in an increasing number from six billion, so, that single chance offers each of them the avenue to imbue it with themselves - "you are the single chance"; if the chance is missed, it can break catharsis for the viewer, as they may feel, in a sense, that they are being left behind.

This comes up most frequently when characters say NeverTellMeTheOdds, and occasionally when someone [[IfMyCalculationsAreCorrect makes a few calculations]]. A good approximation of these odds is the chance of flipping a coin twenty times and getting heads every time.

[[UndeadHorseTrope It is still played straight, but it is also widely parodied.]]

Incidentally, in statistics, odds are defined as a ratio of the probability of an event happening to the probability of it not happening. Saying that the odds of something happening are "a million to one" is actually equivalent to saying that it's a million times more likely to happen than not. The correct expression for something extremely improbable would be a million to one odds ''against''. Many examples omit that bit, but given the nature of this trope, they may not be entirely wrong.

A corollary of the TheoryOfNarrativeCausality. May involve FinaglesLaw, or a CoincidentalBroadcast.

Not to be confused with OneToMillionToOne, or the web game ''VideoGame/OneChance''.

!!Examples:
[[foldercontrol]]

[[folder: Anime and Manga ]]
* In ''Anime/NeonGenesisEvangelion'', Dr. Akagi and her subordinates were fond of proclaiming that the chances of something necessary/spectacular would happen were zero-point-(EleventyZillion zeroes)-one percent; naturally, these things always happened.
* Played straight in ''Manga/MermaidSaga''. However, in this case, the million to one chance of mermaid's flesh granting immortality (without the disturbing side effects) probably ''is'' really a million to one. Over the last eight hundred years, only ''four'' appear to have gained complete and uninhibited immortality, and a few dozen have attained some form of extended life but with body horror or insanity included.
* ''Anime/GaoGaiGar'' actually lampshaded it with its famous catchphrase: "With courage, 1% becomes 100%!".
* In ''Anime/TengenToppaGurrenLagann'', the odds of success were calculated to be 0%. Not 0% as in "so close to zero it might as well be zero", but ''flat-out impossible''. [[BeyondTheImpossible Naturally, the heroes succeed anyway]]. The main character also declares that if the odds of success are "nearly 0%", they might as well be 100%.
* A smattering of AllThereInTheManual makes this happen in ''Manga/DeathNote'': Tsugumi Ohba claims that any time L throws out a percentage chance of Light being Kira (normally 4 to 10 percent), it's really over 90%.
* The premise of ''Manga/DetectiveConan'' lies in the Million To One Chance that a poisonous pill would shrink him into a 6-year-old body instead of killing him. Fortunately for him the creator of the drug was the other person to shrink, so that she could help him.
* Exploited in every episode of ''Anime/YuGiOh'', and all animes based on card games, for that matter: TheMagicPokerEquation is in effect. Although ''technically'', in most cases the chances of a player "miraculously" drawing the card he needs at the right moment (a "topdeck" as some players call it) is one in 40 or better (depending on how many cards are left in his deck, or better if there are multiple copies)), much better odds than a million to one.
* Also happens near the end of ''Anime/CodeGeass''. [[spoiler: For Lelouch and Suzaku to break through the shield of and thus board the Damocles, they have to fly through the opening in the shield made to fire F.L.E.I.J.A.s. In order to do that, they essentially have to disarm a fired F.L.E.I.J.A. using Nina's F.L.E.I.J.A. Eliminator, but that requires real-time environment conditions to be input by Lelouch for 19 seconds before detonation and the Eliminator has to hit within .04 seconds of detonation.]] Odds of success: outrageously low, but the definition of this trope can tell you what happened...
** This was probably not used to show how miraculous the move was, but to show how skilled Lelouch was and how disciplined Suzaku was. The MillionToOneChance bit probably failed to calculate that Suzaku would magically know the exact moment to throw the eliminator thanks to the Geass effect.
* At the end of ''Anime/RocketGirls'', the main characters, falling from 3000 km above the Earth, are expected to disintegrate and burn during reentry. However, they figure they can skip over the top of the atmosphere to shed the excess momentum that threatens them, but [[spoiler:that doesn't work when Akane faints from the G-forces; since she can't provide the timing for rocket burns they need, Yukari has to fire and time the burns by instinct. The result is this charred body of the Mangosteen's pod... but somehow their luck held up and they survived.]]
* Averted with ''Manga/{{Kaiji}}''; whenever something extremely unlikely happens, [[spoiler: it's always due to cheating of some type.]] When not Kaiji doing so, he tends to blame himself for not having good enough luck!
** Zigzagged in ''Manga/{{Akagi}}'' by the same author. Sometimes the mahjong version of TheMagicPokerEquation is because of [[BornLucky characters' luck]], other times it's because they cheat.
* Subverted in a chapter of ''Manga/FrankenFran''. A BornLucky serial killer [[spoiler: dies to the astronomically high odds of being struck by lightning]].
* Subverted in ''Anime/PuellaMagiMadokaMagica''; Kyubey implies to Kyouko that [[spoiler:it's theoretically possible to make witch!Sayaka human again, but extremely unlikely that it would work. Kyouko tries it anyway...and fails, because there's no indication that it is possible either. There's just no evidence that it isn't.]]
* ''Anime/DigimonSavers'': The entire time the heroes are fighting [[BigBad Yggdrasil]], the Computer God of the Digital World, it constantly calculates their chances of winning. "You're chances of winning are exceedingly close to zero." "I calculate a 0.000001% change of you succeeding." And so forth.
[[/folder]]

[[folder:Comics]]
* In Superhero comics, one-in-a-million chance is code for 100% certainty.
* In the ComicBook/DisneyDucksComicUniverse, Gladstone Gander's luck usually beats all odds. Huey, Dewey and Louie even tried to use it against him in the Creator/DonRosa story "Oolated Luck". Donald and Gladstone entered a raffle and Donald's nephews had one entry ticket with Donald's name and the others for Gladstone. Donald won the first prize (a trip in a cruise ship) and Gladstone won the second prize (a lifetime supply of oolated squigs). It turned out Gladstone was lucky for not winning the trip since the ship got stuck in an iceberg. The lucky bastard didn't seem to be concerned for his cousin) And one of the squigs had swallowed a diamond.
[[/folder]]

[[folder:Fan-Fic]]
* In the story FanFic/YetAgain With A Little Extra Help, during a swordsman tournament in the Land of Iron, Sasuke and Tenten are facing each other, and Naruto makes his bet. The two fight out to a ''tie'', and Naruto '''''won all the money on that fight'''''.
--> '''Scabbard''': You flipped a coin when you placed bets on this fight didn't you.
--> '''Naruto''': Yeah, you got me.
--> '''Scabbard''': And [[HeadsTailsEdge it landed on its side...]] didn't it?
* ''FanFic/ThePowersOfHarmony'': One of the abilities of the Element of Laughter is to invoke this trope to the bearer's advantage or that of their allies. Inversely, it can also be used to cause your enemies bad luck.
* The odds might be better than a million to one in this example, but in the tournament finals of ''[[Fanfic/YuGiOhTheThousandYearDoor Yu-Gi-Oh The Thousand Year Door Redux]], both Drake and Kyle are in a no-win situation. It became obvious days ago that this was NotJustATournament, and whoever wins the duel between them will duel one of the Queen's three {{Designated Victim}}s, a situation which, judging by what happened in the first three duels of the semi-finals, will be bad for whoever wins their duel, and worse for whoever the winner duels next. But Kyle does have an idea, although he doesn't have much time to explain it to Drake:
-->'''Drake:''' This better be a good plan, Kyle.
-->'''Kyle:''' Actually, it's a stupid plan, As in, the type you try when you're desperate, and people tell you 'it would never work', but it's the only thing you can think of because you're in a pretty bad situation?
-->'''Drake:''' Like the kind we're in now?
-->'''Kyle:''': Exactly. Still, I seem to remember that when Kaiba gave Yugi that Fiend's Sanctuary card before his duel with Marik, he claimed it would improve Yugi's chances from 3% to 20%. Not the best improvement, but it was enough. So start hoping that slightly improving the odds in our favor will help me pull it off…

[[folder:Film-Animated]]
* In ''WesternAnimation/TitanAE,'' the main character space-floats around a docking bay, when his friend warns him against the chance of an actual docking ship. He responds with, "Oh, please, the chances of a ship docking here are a thousand to one." He then turns around and utters the line, "...and that would be the one."
* Played straight by ''WesternAnimation/ChickenRun'' in the spirit of ScrewDestiny. Being told that the chickens ever escaping Tweedy's Farm is a million to one chance, Ginger retorts "Then there's still a chance."
[[/folder]]

[[folder: Film-Live Action]]
* In the original ''Film/{{Ghostbusters|1984}}'' movie, our heroes manage to stop Gozer by crossing the streams of their proton packs. Egon had earlier warned his comrades against "[[ForbiddenChekhovsGun crossing the streams]]" on pain of being vaporized, but here states that there's "a very slim chance" they'll survive. Since they're the heroes, they do.
* Played totally and completely straight in ''Film/BabyMama'', where Creator/TinaFey's chances of conceiving are a million to one. She goes out and gets a surrogate etc, but by the end of the movie, guess who's pregnant.
* Subverted in ''Film/DumbAndDumber''. When the woman Lloyd is in love with tells him their chances of getting together are one in a million, his response is "So you're telling me there's a chance? YES!" Later he's outraged to find she's married: "What was all that one in a million talk?"
* ''Film/TheEmpireStrikesBack'':
** [=C3P0=] actually does this many times in that movie, sort of a RunningGag. Every time, the heroes seem able to beat the odds he gives them.
-->"Sir, the possibility of successfully navigating an asteroid field is approximately 3,720 to 1!"\\
"Never tell me the odds!"
** "Great shot kid, that was one-in-a-million!"
* ''Film/TheLordOfTheRings'': "Certainty of death. Small chance of success. What are we waiting for?"
* In ''Film/RunLolaRun'', [[spoiler: Lola wins back-to-back spins at roulette on the number 20. Not exactly one in a million, but one in 1,369 -- A 0.073% chance of happening]]. This film is an interesting case. Because multiple outcomes of the same situation are shown, they probably all happened. The other possibilities are just not shown.
* ''Film/TheGamers'' gives us a twenty-to-one chance - mainly on account of there being no one-million-sided dice.
* Lampshaded by Harry in ''Film/WhenHarryMetSally'':
--> "It had to happen at some point. In a city of eight million people you're bound to run into your former wife."
* In ''Film/OctoberSky'', combined with ILikeThoseOdds:
-->'''O'Dell:''' God's honest truth, Homer. What are the chances... a bunch of kids from Coalwood... actually winning the national science fair?\\
'''Homer:''' A million to one, O'Dell.\\
'''O'Dell:''' That good? Well, why didn't you say so?
* In ''Film/BatmanVSupermanDawnOfJustice'', Bruce uses this to justify attacking Superman, claiming that even if there was a 1% chance that Superman could turn rogue, he has to take him down or there would be an even worse casualty number than the Battle of Metropolis.
** He pulls it off again in ''Film/JusticeLeague2017''. [[spoiler:Despite the other members of the League warning him that Superman may not [[UnwantedRevival want to come back]] or [[CameBackWrong may not come back with his morals or mind intact]], Batman is adamant that if there's even a "fraction of a chance" they can use the Mother Box to bring him BackFromTheDead, they ''have'' to take it. Batman ultimately proves correct; aside from a bout of ResurrectionSickness, Superman comes back exactly as he was before he died, and proves instrumental in taking out Steppenwolf.]]
* ''Film/TeenageMutantNinjaTurtles2014'': During the climax, Donatello remarks that they have a [[LudicrousPrecision 0.00000000003% chance]] of stopping the spire on Sacks' tower from falling, and the toxin from contaminating a ten-block radius. Leonardo's response?
-->'''Leonardo''': [[ILikeThoseOdds I'll take it]]. [[{{Determinator}} Nobody moves, no matter what!]]

[[folder:Literature]]
* At some point in ''Literature/{{Animorphs}}'' the reader may sit back and think, "Hey, wait a second. Yeerks are a race with insanely superior weapons. Not only that, but anyone can be a Controller. And this is a worldwide invasion. The heroes are six teenagers who live in a small town in California that can turn into animals? How can they stop the invasion? A bunch of animals couldn't beat the U.S. Army, never mind the Yeerks." This is lampshaded many, many times throughout the series, as the kids admit that at best all they do is slow down the Yeerks from time to time. They mostly lose battles and they agree that they'll never really be able to beat the Yeerks. They do eventually win, due in large part to the morphing technology being so dangerous and versatile. Rachel sums it up pretty well during David's betrayal when the kids are reflecting on how hard it is to kill an Animorph:
--> '''Rachel:''' Just us. Just us against an enemy that could become any living thing. An enemy that could be anywhere, at any time. An owl in a tree, a spider in your house, a cat in the night, and then... Then, when you were unprepared, when you were vulnerable, a lion or a tiger or a bear.
--> I was starting to see why Visser Three hated us so much.
* A running theme in the ''Literature/{{Discworld}}'' novels.
** Memorably [[InvokedTrope invoked]] in the novel ''Discworld/GuardsGuards''. The men of the City Watch are camped out on a rooftop to try to bring down a dragon by [[AttackItsWeakPoint shooting it in its "voolnerables."]] Problem is, they're all GenreSavvy about it, and after considering the situation - their archer used to win prizes for his marksmanship, he's using his lucky arrow, a dragon's "voolnerables" might be quite big - they think that it might ''not'' be a million-to-one-chance of success, but could be a near-certainty, or some awkward number like 999,943-to-one. So they end up trying to handicap their bowman by blindfolding him, putting soot on his face, and making him stand facing the wrong way on one leg while singing [[BawdySong the Hedgehog Song]], but still end up missing the shot. Then the dragon retaliates by flaming the building they are standing on. Which is a [[StuffBlowingUp distillery]]. Luckily, as the narration points out, the odds of the Watch surviving a jump from the (exploding) roof into a nearby pond ''do'' happen to be exactly a-million-to-one. [[spoiler:Later we learn their odds of hitting the dragon's "voolnerables" were more like zero - it was female.]]
** In the very next book ''Discworld/{{Eric}}'', Death informs the mages that Rincewind has exactly one chance in a million of returning from the Dungeon Dimensions. At this stage, the book doesn't even bother to remind the reader of the rule.
*** Mentioning the odds here is more meant to refresh and emphasize Rincewind's ActionSurvivor nature rather than allude to the fact he's due to return.
** ''Discworld/EqualRites'', the third book in the series, is the first one to state that "one-in-a-million chances crop up nine times out of ten", because of [[TheoryOfNarrativeCausality narrativium]]
** Viciously questioned in ''Discworld/TheLastHero'' by Cohen, one of the last surviving barbarian heroes. When he meets the Lady, he tears into her about how many of his fellow heroes died due to taking million-to-one chances that failed them. As he points out, she's the million-to-one chance, and ''also'' all the chances of ''dying''. As such, Cohen has no respect whatsoever for her.
* In ''Franchise/TheHitchhikersGuideToTheGalaxy'' (book, radio show, tv show, movie, etc.), the spaceship "Heart of Gold" has an Infinite Improbability Drive which causes MillionToOneChance events to occur ''all the time''.
** Not just Million to One, ''infinity'' to one, hence the name of the drive. MillionToOneChance events are generated by much simpler (finite) improbability generators, and it is by using one of these that the Infinite Improbability Drive was brought into existence; since such a device is a "virtual impossibility" but not ''completely'' impossible, its existence was a ''finite'', calculable probability. The man who programmed the computers to calculate the precise probability of the Drive's potential existence wound up discovering the exact scientific principles behind the Drive in his results. [[RuleOfFunny And then got lynched by the various eminent physicists who'd tried to create it by more conventional means for being a smartass.]]
** In the Hitchhiker's guide universe, most probabilities are distinct (ie rarely do two highly improbable events have the same probability) which is why it's possible to specify the event you want to occur using a finite/infinite improbability drive. You induce all events with that probability, but usually there's only one or the side-effects of the others are trivial or at least benign. What's even more mindboggling is that the probability that a particularly notable improbable event will have a probability whose digits are particularly notable [[spoiler: such as Ford and Arthur being rescued / 1 over 2 to the phone number of the party where Arthur first met Trillian]] is itself a number which can be plugged into the drive.
** In addition, any event that is infinitely improbable is most likely to instantly happen as soon as the field is turned on.
* '''[[Literature/CiaphasCain Ciaphas Cain, HERO OF THE IMPERIUM!]]''' consciously exploits this. He usually justifies doing so in the narrative by saying that a Million To One Chance is better than no chance at all in those situations, which is what he would have if he ''didn't'' take the risk.
* [[SubvertedTrope Subverted]] viciously in the ''Series/DoctorWho'' ExpandedUniverse novel ''The Book of the War'', where the Remote, a race whose [[PlanetOfHats hat]] is being a living receiver for mass media, have been primed for battle by being exposed to endless transmissions glorifying battle in an effort to make them spontaneous and unpredictable. What the architects of this plan ''didn't'' realize was that the transmissions were so formulaic and [[ClicheStorm full of cliches]] that it had the exact opposite effect. As a consequence, the Remote's first assault had the entire army take the Million to One Shot against the EvilTowerOfOminousness.... and get mowed down by sniper fire. Also an interesting case of DeathByGenreSavviness.
** Although such an army should get mowed down even in cliched media, because of ConservationOfNinjutsu.
* From ''Literature/BridgeOfBirds'':
-->The gods will be forbidden to help you, and none but a mortal can restore you to heaven, and at a conservative estimate the odds against somebody pulling off a trick like that are one in ten thousand billion trillion.
:: Of course, it happens by the end of the book.
* In Jacqueline Carey's ''Literature/KushielsLegacy'' books, heroine Phèdre nó Delaunay is very frequently told (or admits herself) that her plans are madness and suicide. Yet, with the exception of a few UnwittingPawn moments, they always work.
* Played straight as an arrow in "Day of the Ants". The one ant that was carrying a message from the humans trapped under the colony in the mad scientist's lair finds its way to the protagonist, who happens to be the cousin of one of the trapped human. The friend who was with her lampshades this by saying that even if it's a one to a million possibility, there's still one chance of it happening.
* ''Literature/LucifersHammer'': Odds of the Hamner-Brown comet hitting the earth start out at a zillion to one, then they're a million to one, then they're a thousand to one, and then OhCrap!
* ''Literature/DeathLands''. In "Crater Lake" Finnigan faces off with a sec man holding a laser pistol that's so unreliable it only fires one time out of every hundred. This makes Finnigan cocky. And rather gruesomely dead.
* In ''Literature/CharlieAndTheChocolateFactory'', there are only five Golden Tickets in the entire world to be found amongst the millions upon millions of Wonka Bars on store shelves. People with the means to buy many candy bars per day still don't have a guaranteed shot at finding one, so Charlie Bucket, whose family is so poor that a bar of chocolate is a once-a-year birthday treat for him, seems to have no chance at all. Ultimately, he gets ''four'' chances at finding a ticket, and the fourth time is the charm -- on the day before the tour to be held, no less. This is such a good example of this trope that more recent adaptations tend to lampshade/play with it, as in [[Theatre/CharlieAndTheChocolateFactory the 2013 musical]] -- Willy Wonka, while getting acquainted with the tour group, asks Charlie "Aren't you the boy who got his ticket at the very last moment? Don't leave it so late next time." Taken even further in the [[Film/WillyWonkaAndTheChocolateFactory first movie adaptation]] since Charlie thinks the last Golden Ticket had already been found when he bought his two bars. The moment he starts unwrapping his second bar, a news broadcast reveals that the last ticket was a forgery. The only reason he could even afford the chocolate bar with the ticket was because he just happened to find a discarded fifty-pence/dollar bill (practically a fortune to Charlie due to his family's poverty) on the street.
* In the story of Gideon in the [[Literature/TheBible biblical]] ''Literature/BookOfJudges'', {{God}} instructs Gideon to reduce his army to only 300 men and arm them only with torches and pitchers, just so it would be even more obvious that the battle was won thanks to [[DeusExMachina divine intervention]].
* This comes up a lot in ''Literature/TheAffix'' because the titular gem is a causality warper and it's growing in power. One of the weirdest cases is when it makes all six phones in a room ring simultaneously, with six completely different callers with totally unrelated reasons for calling.

* Spoofed in ''Series/RedDwarf'' with the luck virus. Lister, Cat, and Kryten travel to a certain planet to investigate the death of a bacteriologist. While there, Lister is injected with the virus, which allows him to pick all the aces out of a deck of cards. He also tries to hit a dartboard's bullseye while throwing over his shoulder, but the virus wears off and he instead hits the center of Kryten's forehead. In the climax of the episode, [[spoiler:Rimmer goes insane and locks the three in quarantine, slowly draining out the oxygen. Due to the virus however, Lister successfully guesses the code to unlock the door, then manages to trip over the necessary components to cure the insanity while running backwards down a hallway.]]
** Lister, in another episode: "The chances of it happening are one in..." ''[big explosion]'' "...one."
* In the ''Series/DoctorWho'' story "The Creature from the Pit", the Doctor's companion Romana tells him that the odds are 74,384,338 to 1 against his CrazyEnoughToWork plan actually working. He tells her that 74,384,338 is his lucky number. (The plan works, of course.)
* The ''Series/{{Seinfeld}}'' episode "The Fusilli Jerry" has Kramer marvelling at stories told by proctologists, which all end with the statement "It was a million to one shot, doc. Million to one," since none of their patients want to admit they [[AssShove stuck something up there]] on purpose. At the end of the episode, Frank is the victim of such a million to one shot for real, falling on the titular Fusilli Jerry (a sculpture of Jerry that Kramer had made out of fusilli pasta). The final line of the episode (before TheTag) is Frank uttering the same statement.
* ''Series/TomicaHeroRescueForce'' did this, When the BigBad (Baatsu) is unhurt by the "Great God Striker" [[FinishingMove "Super Final Rescue"]] attack which [[ItOnlyWorksOnce cannot be used again]] Hikaru is told that there is a "Less than 0.1 percent chance of victory" instead of giving up he [[spoiler: burrows into Baatsu's head and blows him apart from the inside]] delivering the line:
-->'''Hikaru:''' Your calculations were wrong to begin with! Humans have hearts for helping those in need! With that even 0.1 can be changed into 100 or 1000!
* ''Series/StarTrekTheOriginalSeries'': [[TheCaptain Captain]] [[TheKirk James T. Kirk]] is a master at this - [[TheSpock Spock]] repeatedly [[IfMyCalculationsAreCorrect computes]] incredibly long odds for a successful execution of whatever Kirk's latest daring plan is, often citing denominators in the thousands, if not hundreds of thousands, and Kirk ''almost'' always wins. Eventually, they start [[LampshadeHanging lampshading]] this.
** In "The Naked Time", they have to implode the anti-matter engines to prevent themselves from crashing into a planet that is itself imploding. The procedure has never been done before: Spock and Scotty have only minutes to prep the engines, and they only have one shot to get it right. Kirk insists, "We've got to take that 10,000 to 1 chance!" They do. It works.
** A rare ''aversion'' is in "Errand of Mercy". Kirk decides to break into the Klingon headquarters and kidnap the commander. Spock calculates very long odds against success. They get as far as the commander's office--and are captured.[[note]]Because the Klingon Empire is a PoliceState, everyone--including the commander--is under constant surveillance. The commander's {{Monologuing}} is actually playing for time until Klingon security arrives.[[/note]] Kirk and Spock are only saved by the Organian DeusExMachina.
** An inversion of sorts occurs in "Devil in the Dark", when Spock calculates extremely low odds that both he and Kirk would be killed by the MonsterOfTheWeek, and (unsurprisingly) neither one dies. (Spock's point is raised after Kirk suggests he stay out of the hunt for the monster — ostensibly for his own safety, but really out of concern about Spock's science-minded pacifistic approach.)
* In ''Series/CovertAffairs'' at the end of season 1, Annie is [[spoiler: undercover in London and needs to lose a lot of money, in a non-suspicious way, so that she will not be allowed to the leave the country. She loses all her money playing craps, then takes out a loan for a few thousand dollars, and bets it all on snake eyes -which is very risky. She acts confident that she'll win, but is secretly hoping she'll lose. The roll comes up snake eyes. She cheers, but internally she's freaking out because the whole point was to rack up massive debts. She bets it all on snake eyes again, and his time, she loses.]]
* This sometimes makes the difference on ''Series/MythBusters'' when a myth has to be busted. While the possibility that an occurrence could happen, the myth's conditions are so difficult to replicate beyond pure fluke that the myth has to be busted (usually when dealing with myths that question the practicality of some far-fetched idea).
* In ''Series/TheHitchhikersGuideToTheGalaxy'', Arthur and Ford are rescued by the Heart of Gold seconds before they would have died after being ejected from a Vogon ship. Arthur states that the chances against it were astronomical after Ford tries to act as if he was counting on it as a certainty. Because Arthur had lived his entire life on Earth and Ford had been stuck there for over a decade, the ensuing weirdness such as an infinite number of penguins with a revised script for ''{{Hamlet}}'' didn't tip them off to the fact that they had an advantage in the form of the Infinite Improbability Drive.
* Not at all rare in the Franchise/StargateVerse, but a particularly well-lampshaded version happens in ''Series/StargateAtlantis'' when Rodney and Jeannie almost destroy an alternate universe. The goal is to draw energy from a parallel universe but the process would create dangerous exotic particles in the alternate reality. Carter assure them this won't be an issue, though, since "the odds of us choosing at random one that’s inhabited are astronomically slim." Surprise, surprise: they choose an inhabited one. And not just ''any'' inhabited universe, but one similar enough to their own that everyone in the main cast has counterparts there.
* In an episode of ''Series/GilligansIsland'', a radioative meteorite falls on the island, and the crew is in danger of the radiation killing them. They learn of an incoming storm, and the Professor gets the idea of trying to put a lightning rod on it and hope lightning strikes it, but admits the chance is a million to one. When the Skipper asks what could be worse than that, Gilligan [[SmartBall suggests]], "A million to none?" Realizing that he has a point (slim chance is better than no chance) they try it, and it works.
* Invoked in ''Series/{{Castle}}'' when Beckett was trapped on a pressure-sensitive bomb;
-->'''Beckett''': Castle, please, you have to leave me, there's no reason for both of us to die.\\
'''Castle''': Oh, I didn't come here to die, I came here to defuse the bomb. There's still a chance.\\
'''Beckett''': Yes, a one-in-one-hundred-thousand chance!\\
'''Castle''': Great, while there's still a chance, I'm not giving up.
* PlayedForDrama in, of all things, ''Series/HannahMontana''. When Miley needs surgery done on her vocal cords and she's worried about the surgery being botched, ending her career. The doctor reassures her that the likelihood is one in a million. Considering that's what Miley was told her chances at stardom was, she's even more worried because of her track record for million-to-one chances. However the surgery goes off fine.
* Subverted in ''Series/ParksAndRecreation'' in "Win, Lose, or Draw," the climax of season five's [[spoiler: election]] arc. Throughout the episode, there are several hints that the end result will be [[spoiler: an exact tie between Leslie and Bobby Newport[[note]]The rules for a tie are discussed, Leslie laments that she didn't write a tie speech, Jerry forgot to vote, a TitleDrop[[/note]]]]--not one in a million, but astoundingly improbable, in an [[spoiler: election with several candidates and many thousands of voters. At first, it appears that Leslie has lost by twenty-two votes, but a recount proves that she actually won by the same number.]]

* This trope is very common among the top babyfaces in Professonal Wrestling. So common, in fact, that the fans became very GenreSavvy when WWE attempted to [[InvokedTrope invoke this trope]] on Wrestling/JohnCena. Thanks to this, his already simmering and vocal {{Hatedom}} just got louder, citing his status as an InvincibleHero, and each pay per view ended up as a monthly "pay to watch John Cena overcome impossible odds once again" event to them. The culmination was at 2006's New Year's Revolution pay per view, where Cena was the first in the Elimination Chamber, surviving through 5 men while having about 90% of the fans in attendance against him. The crowd seemed ready to riot. [[spoiler: Then Edge, one of the most hated men in the company at that time, backdoored his way into a match right after this and subverted this trope, defeating Cena to win his title despite being fresh and Cena having just fought through five men in a steel cage. The crowd was so happy to see this subverted that Edge became one of the biggest stars in the company almost overnight.]] Cena's hatedom has since cooled down when WWE downplayed him being a one-man odds beating machine.
* Of course, John Cena is far from the worst offender of invoking this trope. Wrestling/HulkHogan in WCW was doing this to such a degree that C-3PO's head would explode trying to calculate the odds. The 1996 Uncensored PPV had Hulk Hogan team up with his then buddy Wrestling/RandySavage to take on the Alliance to End Hulkamania. Wrestling/RicFlair, Wrestling/ArnAnderson, Wrestling/{{Meng}}, Wrestling/TheBarbarian, Wrestling/LexLuger, Wrestling/KevinSullivan, Z-Gangsta (Zeus), and The Ultimate Solution. That's right, an 8 on 2 advantage, [[InSpace in a triple-decker steel cage]]! [[spoiler: Hogan wins.]]

* In ''VideoGame/HalfLife1'', Gordon is cheerfully reminded by his fellow scientists that ExplosiveOverclocking of their AppliedPhlebotinum is perfectly okay, because a "resonance cascade scenario is extremely unlikely". They also assure you that "[[WhatCouldPossiblyGoWrong nothing will go wrong]]"...
* Kyosuke Nanbu from ''VideoGame/SuperRobotWars'' ''loves'' this trope. After all, his CatchPhrase is ''"I don't mind betting on the tough odds!"''
* Played with in ''VideoGame/PennyArcadeAdventures'' Episode 1, where the chance of a summon working is stated as 1 in millions (if not billions), but it's really more like 1 in 4.
* The final battle of ''VideoGame/StarFoxAssault'' has the final boss mention a zero chance of victory for the protagonists. It is entirely possible to win the battle; however, the announcement of the zero chance is in fact an attempted MindScrew by the BigBad.
* In ''VideoGame/{{Portal 2}}'', [[EnemyMine GLaDOS]] gives this evaluation of the player character's chances of winning the final battle:
-->'''[=GLaDOS=]:''' I'll be honest, the odds are a million to one, and that's with some generous rounding. But if we're going to explode, let's at least explode with some dignity!
* In ''VideoGame/{{Discworld}}'', Rincewind has to collect a number of {{Plot Coupon}}s (tattoo, sword that goes ''ting'', secret identity, camouflage...), but not before determining, with the aid of Nobby, which ones would land his chance of success at exactly a million to one.

[[folder: Visual Novels]]
* ''VisualNovel/HigurashiWhenTheyCry'' has its entire premise based around this. [[spoiler:It's about Rika living through every possible world in a GroundHogDayLoop, to try to find the one world where she doesn't get horribly killed.]]
** Actually a recurring theme in the Franchise/WhenTheyCry [[TheVerse verse]]. In ''[[VisualNovel/UminekoWhenTheyCry Umineko No Naku Koro Ni]]'', Kinzo relies on a huge gamble involving the epitaph to [[spoiler:give Yasu the headship and get them to forgive him]] as evidenced by the quote on top of the chapel: "You will only be blessed at a probability of a quadrillion to one." In the same EP, Bernkastel tells Lion and Will that the chances of Lion existing in a fragment is about 1 out of 2,578,917. [[spoiler:And later on, cruelly reveals that in all those fragments, Beatrice/Lion suffers the same dead-end fate.]] [[{{Determinator}} Not that it stopped either Will or Lion.]]

[[folder: Web Comics]]
* Subversion in ''Webcomic/GirlGenius'':
--> '''Abner:''' There's a ''million'' reasons why that is ''not'' going to work.
--> '''Dimo [referring to himself, Maxim, and Oggie]:''' ''Dun vorry''. Dere's ''three'' reasonz it ''iz''.
* In ''{{Webcomic/Homestuck}}'', [[ParodySue Vriska's]] entire plan to take out Jack Noir relies on rolling the best possible result on eight magical eight-sided dice (a 16,777,216 to 1 chance), unleashing their ultimate magical attack. It would have ''worked'' -- because she'd been "stealing ALL of the luck" from her [[DoomMagnet entire team]].
* [[SubvertedTrope Subverted]] and [[LampshadeHanging lampshaded]] in ''Webcomic/TheOrderOfTheStick'' [[http://www.giantitp.com/comics/oots0454.html #454]], when Haley relies on her [[GenreSavvy Genre Savviness]] a bit too much.
-->'''Durkon:''' Lass, it were an awful difficult shot.
-->'''Haley:''' Exactly! It was totally dramatic! How did I miss?
** Spoofed and [[LampshadeHanging lampshaded]] again in [[http://www.giantitp.com/comics/oots0584.html #584]]. Being even more GenreSavvy than the rest of the group (Durkon's response to the above is "I think maybe ye been spendin' too much time wit Elan"), Elan realizes that a 10% chance of an imp summoning a demonic ally isn't anything to worry about, but a million-to-one chance of the imp summoning a monster that could actually kill them is a sure thing. This results in one of the page quotes.
-->'''Vaarsuvius''': ''(sigh)'' And once again, Probability proves itself willing to sneak into a back alley and service Drama as would a copper-piece harlot.
* Justified in ''Webcomic/SchlockMercenary'' when Gav goes through a wormgate and immediately dies at the hands of a hostile guard that he had sent through the wormgate before. And meets up with his scientist buddies out of harm's way. Turns out that Gav went through the wormgate when it was set to send duplicates to all the other wormgates - meaning that Gav hit both those million-to-one shots by simply playing the odds ''950 million times.''
-->'''Aylee Bot''': "There are now 950 million of you. According to the latest available galactic census data, blue-haired, Caucasian human males are now the largest single sapient ethnicity in the galaxy. You outnumber several entire sapient species. You are no longer merely human. You have become your own, weird demographic."
* In ''We're Misguided'', an experimental [[http://www.rpg.net/news+reviews/comics/misguided30jul01.html billion-sided die]] is unveiled. Rolling it is [[http://www.rpg.net/news+reviews/comics/misguided06aug01.html not a good idea]].
-->'''Minty Fool''': Finally gamers will be able to calculate even the slimmest odds.
-->'''Miss Guided''': Like their chances of ever finding dates?
* In ''Webcomic/TheWaterPhoenixKing'', this is actually used as a THREAT. Anthem points out that even though she only has a one in twenty chance of killing Demon-Dragon Darumatha, [[KarmicDeath this is still a one in twenty chance that Darumatha permanently dies because she wanted to swat a fly and had little else to gain.]] [[DidyouJustScamCthulhu This is actually enough to make the demon-dragon concede.]]

[[folder: Web Original]]
* In ''WebVideo/{{Tabletop}}'', The odds of [[spoiler: [[Creator/{{Nigahiga}} Ryan Higa]]'s feat of rolling ten brains on his first turn in ''Zombie Dice'']] approach '''infinity'''. Creator/WilWheaton speculates that, in order to balance his luck out, somewhere in the universe a planet spontaneously imploded.
* Some of LetsPlay/{{Chuggaaconroy}}'s victories throughout his ''Franchise/{{Pokemon}}'' [=LPs=] definitely count:
** Finding and catching a [[VideoGame/PokemonGoldAndSilver shiny Koffing]].[[note]]Finding a Shiny Pokémon in general is a 1 in 8,192 chance. Catching it is even less likely.[[/note]]
** Catching [[VideoGame/PokemonRubyAndSapphire Groudon]] in a freaking ''Nest Ball''. [[NoIndoorVoice His reaction certainly says so as well.]]
*** Likewise, the capture of Latias from the same [=LP=]. Given the very improbable conditions at the time [[spoiler:(a level 50 Pokémon at full health, also with a Nest Ball)]], his odds were just '''0.4%'''.
* When the ''WebVideo/GameGrumps'' played the Playstation 2 ''Wheel of Fortune'' game, Danny landed on "Lose a Turn" four times in a row. As one comment points out:
--> '''[=Supermutant6112=]:''' Alright, there are 24 spaces on the board. Every single turn, there is a 1 in 24 chance of landing on the "Lose a turn" spot. This means that Danny had a (1/24)^4 chance of getting FOUR turns lost. That is one in three-hundred-thirty-three-thousand-seven-hundred-seventy-six, or, to put it in simpler terms, [[BornUnlucky three in a million.]]﻿
* The video where a guy playing ''VideoGame/TeamFortress2'' gets killed though a exploit involving a tiny unnoticeable crack in the wall. While he's looking for the crack in the wall a week or so later, the ''same guy'' that did that to him randomly joins the game and runs into the correct spot (which should be mentioned needs to be near pixel perfect) seconds after the guy finds the crack for the first time, allowing him to get revenge by killing him in the same exact manner. [[https://www.youtube.com/watch?v=1vAOp_hSOv8 Seriously... What Are The Odds!?]]

[[folder: Western Animation]]
* Inverted in an episode of ''WesternAnimation/DynomuttDogWonder''. Dynomutt is reprogrammed for evil and given the task of killing his master, Blue Falcon. Falcon, knowing [[TheDitz Dynomutt's]] [[UnwantedAssistance tendencies all too well]], announces that the odds are a million to one... in his favor. (And yes, the odds do hold up this time.)
* Played straight in ''Series/{{Thunderbirds}}'', of course. "That thing [aircraft heading towards the tower they're in] is never going to hit us! It's a million to one chance!" Guess what happens. Go on.
** Subverted in the first episode when the authorities try a desperate plan to board a plane in mid-air and the chances are explicitly described as a one in a million chance. As it happens, it doesn't work.
* ''{{WesternAnimation/Futurama}}'' hangs a lampshade on it when Fry tries to use the Earth's most powerful radio telescope to find Bender somewhere in the universe. After spending a few days searching, Leela notes that even if he spends his whole life looking for Bender, he'll have searched less than a ten-thousandth of the universe. As he gives up, he spins the viewfinder aimlessly and says "I wish I had Bender back!" - which just happens to reach the ears of a God-like being that is conversing with Bender, and promptly sends him back to Earth. Leela's comment on this is priceless:
--> '''Leela''': "This is, by a wide margin, the ''least likely thing that has ever happened!''"
** ''Futurama'' has another brush with odds when Bender becomes an Ultimate Robot Fighter. After his manager notes that his antics are getting stale, he is pitted against 500-ton Destructor while wearing a tutu. The announcers note that the odds on Bender are ''infinitely'' low:
--> '''Rich Little''': "The Vegas odds tonight stand at an unprecedented 1000:0. A bet of zero dollars on Bender pays \$1000 if he wins. Still, very few takers."
--> '''George Foreman''': "It's not- not a smart bet."
** It ends up being subverted as Bender loses when Destructor falls on him.
** In another extreme subversion, Kif tells Zapp Brannigan that at present speed, there is a ''one hundred percent'' chance of the ship being sliced in half. Brannigan says to maintain present speed, and the ship is sliced in half, losing all crew.

[[folder: Real Life]]
* [[http://www.ksl.com/index.php?nid=148&sid=11943102 This man]]--it's a "45 billion to one chance", rather!
* A literal million-to-one roll happens [[http://unicornjelly.com/urulesmystories.html#mil here]].
* It turns out, quite a lot of things in real life exhibit this trope. Many events that are assumed to have their chances controlled by the normal bell curve distribution, have actually been found to obey Mandelbrot's (yes, he of the pretty fractal patterns) fat-tailed distribution. Which means that improbable events actually happen more often than statisticians expect.
* The managers of the hedge fund, Long Term Capital Management, said that there was only a one in a billion chance that their investment strategy would falter. Four years after it was founded, it collapsed, nearly taking the world economy with it.[[note]]One major reason for the collapse was that LTCM was no longer following that strategy, but rather a variant of it. Another reason is that they gamed their strategies using computer models, forgetting that actual investing is done by human beings, who do not always act with complete rationality.[[/note]]
* An exception to the rule is perhaps worth mention here. [[http://www.boingboing.net/2008/09/04/lhc-will-not-destroy.html One scientist]] has said that the Large Hadron Collider has less than a one in 10^billion*billion chance of destroying the world. Far more energetic events (meteoric impacts, volcanic eruptions, earthquakes, etc.) take place on Earth on a regular basis. Yet the [[GenreSavvy invocation of this]] [[WrongGenreSavvy trope to real life]] makes that chance seem far scarier than it should. (The same scientist said, likely tongue-in-cheek, that one has a one in a hundred billion chance of spontaneously evaporating while shaving. It's probably less than that.)
** The Russian mathematicians Irina Aref'eva and Igor Volovich did the numbers and it turns out its rather more likely that someone in the future will lock onto one of the incidental wormholes the LHC's collisions might make for passing moments, and use them as a 'year zero' for a future time machine to come visit us.
* UsefulNotes/RichardDawkins mentions in ''The God Delusion'' that if the chances of life arising on any given planet was one in a billion, then life would still have arisen on a billion planets in the universe, using one of the lower estimates of a billion billion planets in the universe (the actual figure is probably much higher). This astonishing figure relies on the fact that while a one in a billion chance is much too small for humans to comprehend comfortably, with a large enough sample a billion to one becomes a certainty. And the existence of life on this planet is an example of this certainty.
** The chances of life arising (and forming a technological civilization) are collected in the [[http://en.wikipedia.org/wiki/Drake_equation Drake Equation]], which predicts how many technologically advanced civilizations should be in existence. The problem is that the vast majority of terms in the equation are probabilities which require broad speculation. As we learn more about the nature of the universe, the ''uncertainty'' of terms in the equation goes down, which is not the same thing as the ''probability'' of other sapient, technologically advanced life existing.
*** There's also a discussion on the definition of probability here, where frequentists will claim the true probability is the same - it's just calculated it incorrectly. Another group disagrees and has a different definition. But that's a separate discussion.
* Rare diseases deserve a mention here. It's true that there are diseases that affect only one in every 10,000 or 100,000 people, but it's also true that ''hundreds'' of these conditions have been identified, and there are almost certainly hundreds more that are as yet unidentified. So don't be shocked if you or someone you know is diagnosed with a rare disease - perhaps ''that'' disease is rare, but rare diseases in total affect a lot of people. Odds are you know or will know someone with one.
** And so, JustForFun/TelevisionIsTryingToKillUs. The real-life lesson taught to all medical providers is summed up as, "When you hear hoofbeats, think horses, not zebras." [[CompletelyMissingThePoint Unless you're in Africa.]] In other words, when a patient comes in with a set of signs and symptoms, start looking for the common sources of those signs and symptoms before you start thinking about weird diseases. From a patient care viewpoint, it makes sense; if someone comes into the ER with low blood sugar and altered mental status, starting immediate treatment for diabetic shock is almost always better than figuring out all the other strange ways the patient might have low blood sugar and AMS. The problem is that thanks to Hollywood and the news, "millions of diabetics averting catastrophe and remaining fairly healthy thanks to managed diet, exercise, insulin," isn't news, but "man dies of rare illness doctors mistook for diabetes," is. The public winds up WrongGenreSavvy, often thinking they have weird diseases rather than simple ones, or else expecting whole battery of tests when the answer is obvious from just a couple of blood tests and a quick examination. [[Series/{{House}} Dr. House]] hasn't helped matters much, and countless medical practitioners subtly curse that show (even if they're some of the biggest fans). So ([[EaglelandOsmosis should you be an American)]], yeah, you will likely know one person in your life with Tay-Sachs, Gauchier's, Huntington's, or something equally rare. [[http://www.cdc.gov/NCHS/data/nvsr/nvsr58/nvsr58_19.pdf Almost everyone]] else you know will die to cardiovascular disease, malignant neoplasms, kidney or mental diseases, liver failure, the flu, and the occasional accident, murder, or suicide.
* This is pretty much how national/international lotteries can be successful. The chances of winning might be one in 75 million, i.e. all but impossible. But with hundreds of millions of entrants, there is in all probability going to be a few winners of the vast jackpot, which sells the dream to the next hundreds of millions of entrants.
* When dealing with continuous random variables (almost anything with an infinite number of possible outcomes), each individual outcome will occur with probability of one over infinity. They're not talking one-in-a-million, but so close to zero-in-a-million it can't be comprehended. However, one outcome ''always'' happens despite technically [[LiteralMinded being impossible]]. Hence the word ''almost''.
** Consider a square with sides one meter long. Now consider the diagonal of that square as a line. The probability of a randomly chosen point within that square - remembering that that square has an infinite number of points within - being within a certain region is P = (area of region) / (area of square). Now, a line has one dimension. Hence, the line has a length, but zero area. Therefore, the P of a randomly chosen point landing on the line segment = 0/1 = 0. Yet it's possible. This is where mathematicians split hairs between [[http://en.wikipedia.org/wiki/Almost_sure ''almost sure'']], happening with P = 1, and ''sure'', happening always, no matter what. As a matter of fact, whatever point does wind up chosen had a P = 0 chance of being chosen, so [[PuffOfLogic it had an assigned probability of 0, for no-way-no-how, but still happened.]]
** Whether the probability of such an event should ''actually'' be considered zero is subject to argument. There are number systems (for example, the hyperreal numbers) which permit "infinitesimal" values. This solves the apparent contradiction because then the probability of the events described above is not zero and it makes sense that they can occur. Such number systems bring in problems of their own, though, and currently suffer from a lack of popularity.
* Fans of TabletopGames are usually woefully unable to appreciate what the odds of something happening actually are. Consider a popular house rule for some games where an attack is rolled on a 20-sided dice. If a twenty is rolled, it is rerolled with a chance for [[CriticalHit massive bonus damage]]. If a second twenty is rolled, the target is dramatically slain. Now, let's say that each character is subjected to only twenty attacks in a game. The odds of any one attack pulls this off is only one in 400, so nothing to worry about, right? Well, over the course of ten gaming sessions, it becomes almost a 40% chance of being killed just by this mechanic. In a six person group, over ten sessions, it's more than 95% probably a player is instantly killed like this. And if you're playing the [[TabletopGame/DungeonsAndDragons granddaddy of TT games]], considering it usually takes at least four-six or so sessions to go up a level...
* Magic tricks abuse this all the time. The reason that a magician's ability to always cut to your card and produce it on command seems surprising is because you don't perceive the trick. Even if you know it's a trick, the visuals help maintain that what you saw happen was what actually happened. Therefore, the odds that the magician can successfully produce your card is apparently one in fifty two. Of course, it's really almost one in one, and if you know the secret to a given trick, it's obvious why.
** Playing with the odds here leads to a fun trick, wherein the target picks a card, and then the "magician" finds all sorts of bizarre ways to ensure that the card cannot be tracked... then draws the top card of the deck. 51 times out of 52, it's a joke trick. The fifty-second, you blow someone's mind. Extra fun to use on magicians who are watching for the sleight, and will never find it.
*** You'll need to know quite a few magicians in order to have a good chance of pulling it off in front of even one. Also, most magicians are wise to such sophistry and if irked can really make the performer look like a fool. Just ask him to repeat it at the next gathering. And the one after that, if necessary. Then show them up with a few actual tricks.
* Affirmed in any case of the [[http://en.wikipedia.org/wiki/Birthday_Paradox Birthday Paradox]], where a group of just 23 people will have a 50% chance of having at least one birthday in common. The reason is because for every additional person added to a group you add a number of comparisons equal to the number of persons already in the group. Birthday Paradoxes often result in [[MindScrew counter-intuitive]] outcomes with UnfortunateImplications. For example a DNA test that can narrow down a match between two random people to a probability of 13 billion to one will on average yield [[http://freakonomics.blogs.nytimes.com/2008/08/19/are-the-fbis-probabilities-about-dna-matches-crazy/ 100 exact matches]] in a sample prison population of just 65,000. Can also be used [[http://en.wikipedia.org/wiki/Birthday_attack to attack]] high strength cryptographic algorithms.
* Steve Whiteley bet £2 on a horse that had lost the last 26 races. It won the race and as the only person who bet on this horse he won a jackpot of £1,445,671.71. [[http://www.racingpost.com/news/horse-racing/lupita-exeter-exeter-tote-small-stakes-racegoer-scoops-1-4m-jackpot/827203/]]
* The odds of a random person being struck by lightning and surviving in any given year are 1:280,000. The odds of three brothers all being struck by lightning and surviving is 1:345,000,000. The odds of three brothers all being struck by lightning ''in the order in which they were born'' and surviving is 1:2,700,000,000. This very thing happened to brothers Jack, Aaron, and Nathan Helms of Apopka, Florida.
** This is related to the rare diseases example above. A probability of 1 in 3 billion sounds very low, but you have to consider what the "positive" outcomes are. What if three cousins were hit in the order on which they were born? Or maybe in alphabetical order? If you count all newsworthy events you can quickly get a very reasonable probability.
* The Helms brothers have ''nothing'' on [[http://en.wikipedia.org/wiki/Roy_Sullivan Roy Sullivan]]. He was struck by lightning and survived on ''seven different occasions'', the odds of which being a whopping 1:10,000,000,000,000,000,000,000,000,000.
** Unless, of course, there's something in Sullivan's lifestyle, genetic makeup, or other circumstances that makes him more likely to be hit by lightning. Lightning strikes are not truly random occurrences.
** [[DeathByIrony And then he shot himself.]]
* NASA's management claimed that the risk of catastrophic malfunction on the shuttle was 1 in 100,000. After the Space Shuttle Challenger disaster, UsefulNotes/RichardFeynman immediately realized that this claim was risible on its face; as he described, this assessment of risk would entail that NASA could expect to launch a shuttle every day for the next 274 years while suffering, on average, only one accident.
* The chances of one meeting a frighteningly similar-looking {{Doppelganger}}, or DistaffCounterpart, to oneself on any given day are quite low but over the course of a lifetime the chances are good that people encounter a few.
* Chances are good that [[NamesTheSame someone out there shares your name]], even if it's a fairly unusual one. Not only might they have the same first name as you, they might even have the same last name! People tend to pick names for their kids that they like and/or find [[MeaningfulName meaningful]], and there's a good chance that what your parents thought was an AwesomeMcCoolName, another parent will too. Every year, there's a list of top-ten trendy baby names. Many parents also name their kids after a family member, a famous person, a saint, deity, or [[Literature/TheBible Biblical]] figure, etc.
* One micromort (the measurement of the probability of death) is equivalent to an activity that has a one-in-a-million chance of a fatal accident occurring.
* Mathematicians have determined that any event with odds of 10 to the 50th power or greater is impossible. This figure takes into account the age of the universe. What are the odds of a simple protein molecule, something that even the simplest cell contains millions of, coming into existence by chance? 10 to the 65th power! Sir Fredrick Hoyle calculated that the odds of a simple cell forming by chance is 10 to the 40,000th power! An adult man weighing 70 kilograms would have around 70 trillion cells in his body.
* When you think about it, your own '''birth''' qualifies as this trope. While a human mother usually only has one egg cell in the fallopian tubes when she's able to get pregnant, a single ejaculation from a man can release anywhere from 40 million to 1.2 billion sperms cells. And ultimately, [[ThereCanOnlyBeOne only one sperm cell will be able to fertilize the egg]] while the others perish. This means that any individual sperm cell's chance of getting to fertilize is almost zero, and yet the fact remains that one sperm cell ''will'' get to fertilize the egg. Not only that, but an estimated ''30-90%'' of fertilized eggs either fail to implant in the uterus, or perish shortly thereafter. (And that's just under ''natural'' conditions.) In short, you simply being born the way you are pretty much fits this trope to a tee.
* Many animals, especially R-strategist ones such as fish, aquatic invertebrates, insects and rodents, tend to [[ExplosiveBreeder produce hundreds of eggs at a time]], the record holder being the Mola Mola, who can produce 300 million eggs in one spawn. The chances of offspring surviving to adulthood is so low that of those eggs, only one or two may make it to breed themselves.
* In January of 2016, off-duty sheriff's deputy Jose Marquez got into a shootout with two robbers in an apartment parking lot in Aurora, Colorado. During the gun battle, one of Marquez's bullets actually went straight down the barrel of a robber's gun. Police described such a shot as "one in a billion."[[http://www.cbsnews.com/news/deputy-fires-one-in-a-billion-shot-suspect-gun-barrel/]]
* Since there's currently 7 billion people in the world, there are roughly 7,000 Million to One chances occurring.
