A coin toss is a simple method used to make a decision or settle a dispute by flipping a coin. The coin has two sides: heads and tails. When the coin is tossed into the air, it spins and lands on one of these sides, which determines the outcome. This method is often used in games, sports, and other situations where a quick decision is needed. The fairness of a coin toss relies on the assumption that each side has an equal chance of landing face up, typically 50%. This randomness makes it a popular choice for resolving choices, such as who goes first in a game or which team starts with the ball in sports like football or basketball.
