Coin Flipping

probability · games · randomness · decision-making

Two equal chances. When you flip a fair coin, there's a 50-50 chance it lands on heads or tails, making it a perfectly balanced way to pick between two choices.

Ancient history. People have been flipping coins for thousands of years to make decisions and settle disagreements, long before they were used in sports.

True randomness. A coin flip is unpredictable, meaning no one can know ahead of time which side will land up, which is what makes it fair for deciding things.

Sports tradition. In football, basketball, and other sports, teams flip a coin at the start of the game to fairly decide who gets the ball first.

Mathematical magic. Mathematicians study coin flips to understand probability and randomness, and it's one of the simplest ways to learn how chance works.
