How a Coin Flip Works

A coin flip is one of the simplest and most widely used methods for generating a random binary outcome. In a fair coin toss, there are exactly two equally likely outcomes: heads and tails, each with a probability of 50% (or 1/2).

This simulator uses a pseudorandom number generator to produce results. For each coin, a random number between 0 and 1 is generated. If the number is less than 0.5, the result is Heads; otherwise, it is Tails. This provides a uniform 50/50 distribution over many flips.

Coin flips follow the binomial distribution. When flipping N coins, the probability of getting exactly K heads is given by the formula: P(K) = C(N,K) * (0.5)^N, where C(N,K) is the binomial coefficient "N choose K." The statistics panel tracks your results so you can observe how they converge toward the expected 50/50 split over time.
