Probability Guide: Coin Toss Mechanics & The Law of Large Numbers
Why is a coin flip the universal 50/50 benchmark?
A fair coin toss provides a symmetrical binary sample space. Our simulator utilizes CSPRNG crypto.getRandomValues() to guarantee unbiased 50.00% odds on every single toss.
The Law of Large Numbers
As the sample size increases toward hundreds or thousands of flips, the observed percentage of heads and tails strictly converges to the theoretical 50% distribution.
