Presets
Flip a coin a few times and the proportion of heads jumps around wildly; flip it thousands of times and it settles onto the true probability. That is the law of large numbers — averages converge even though individual flips stay random. Crucially, it does not mean a run of tails is "due" to reverse; that belief is the gambler's fallacy.

Governing equation
Reading this result: With a near-fair coin the running proportion wanders wildly at first, but the law pulls it toward 0.50 as flips pile up — and a streak of tails never makes heads “due.”
