Note that the three-way flip is 75% likely to work each time it is tried (if all coins are heads or all are tails, each of which occur 1/8 of the time due to the chances being 0.5 by 0.5 by 0.5, the flip is repeated until the results differ), and does not require that "heads" or "tails" be called.Ī well-known example of such a three-way coin flip (choose two out of three) is dramatized in Friday Night Lights (originally a book, subsequently film and TV series), wherein three Texas high school football teams use a three-way coin flip. To choose one out of three, the previous is either reversed (the odd coin out is the winner) or a regular two-way coin flip between the two remaining players can decide. To choose two out of three, three coins are flipped, and if two coins come up the same and one different, the different one loses (is out), leaving two players. Three-way coin flips are also possible, by a different process – this can be done either to choose two out of three, or to choose one out of three. Some high-profile coin tosses, such as the Cricket World Cup and the Super Bowl, use custom-made ceremonial medallions. Larger coins tend to be more popular than smaller ones.
The coin may be any type as long as it has two distinct sides it need not be a circulating coin as such. Such cases in which a coin does land on its edge are exceptionally rare and in most cases the coin is simply re-flipped. Angular momentum typically prevents most coins from landing on their edges unsupported if flipped. A computational model suggests that the chance of a coin landing on its edge and staying there is about 1 in 6000 for an American nickel. However, even on a flat surface it is possible for a coin to land on its edge. It is possible for a coin to land on its side, usually by landing up against an object (such as a shoe) or by getting stuck in the ground. When the coin comes to rest, the toss is complete and the party who called correctly or was assigned the upper side is declared the winner. Depending on custom, the coin may be caught caught and inverted or allowed to land on the ground. The other party is assigned the opposite side. Either beforehand or when the coin is in the air, an interested party declares "heads" or "tails", indicating which side of the coin that party is choosing. Process ĭuring a coin toss, the coin is thrown into the air such that it rotates edge-over-edge several times. In England, this was referred to as cross and pile.

Coin flips are also often used in politics in which a coin is tossed when two candidates poll an equal number of votes. For instance, in cricket, the toss decides who gets to bat or bowl first, whereas coin flips in tennis decide which player is given the opportunity to serve first. It is a surprise that this tradition was carried from ancient times, when superstitions reigned supreme, into modern times and is still used in numerous sports today. Though the origins of the holiday are inconsistent, the game has existed in the world since the days before technology. To celebrate this very notion, Flip a Coin Day was formed and is celebrated across the U.S. It is stories like these that have made coin tosses a helpful way for making choices. In fact, in 1903, it is a coin toss that provided Wilbur Wright with a chance to make history! Yes, the first attempt to fly was made after a simple coin flip decided whether Wilbur Wright or Orville Wright would fly first. For example, the singing legend Ritchie Valens lost his life after a fateful coin toss placed him in a horrifying plane crash. For many, a coin toss can decide their fate, therefore, the coin flip is seen as a way for God or a higher power to push forth his will and communicate what he feels the right choice is. Coin flipping is one of the easiest games of chance and is often used by people to make important decisions.
