Practice of throwing a coin in the air to choose between two alternatives
For other uses, see Heads or Tails (disambiguation). For the use of "Heads and Tails" in computer programming, see CAR and CDR. For coin tossing in cricket, see Toss (cricket).
Coin flipping, coin tossing, or heads or tails is the practice of throwing a coin in the air and checking which side is showing when it lands, in order to randomly choose between two alternatives, heads or tails, sometimes used to resolve a dispute between two parties. It is a form of sortition which inherently has two possible outcomes. The party who calls the side that is facing up when the coin lands wins.
