How Does a Coin Flip Work?

A fair coin flip gives exactly 50% probability for heads and 50% for tails on every single flip. Each result is completely independent of all previous flips — this is known as an independent event in probability theory. No matter how many heads appear in a row, the next flip is always 50/50.

When to Use a Coin Flip

Coin flips are a quick and fair way to make decisions when two options are equally valid. Common uses include deciding who goes first in a game, settling small disagreements, sports — the coin toss before a football or cricket match is a long-standing tradition — and any situation where you need an unbiased random choice.

Is This Coin Flip Fair?

Yes. This tool uses JavaScript's Math.random() function which generates a random number between 0 and 1. Values below 0.5 result in heads, values above result in tails. The probability is exactly 50/50 on every flip.
