In probability theory, small sample sizes can be misleading. Flip a coin 10 times and you might get 30% or 80% heads. But flip it 10,000 times and the frequency will almost certainly be very close to 50%.
This experiment demonstrates this convergence. It flips coins from 1 to your chosen maximum, recording the percentage of heads at each step. The graph shows how the frequency approaches 50% as the number of flips increases.
