When to Use a Coin Flip
Coin flipping is one of the oldest and simplest methods for making fair binary decisions. Use it to settle disagreements, decide who goes first, make quick choices between two options, or demonstrate probability concepts. In sports, coin tosses determine which team kicks off or chooses sides. In decision theory, a coin flip can help overcome analysis paralysis by forcing a choice.
