Probability & Distributions

The law of large numbers says that as you repeat an experiment, the observed frequency of each outcome approaches its theoretical probability. Rolling 2 dice produces a triangular distribution peaking at 7 — there are 6 ways to make 7 but only 1 way to make 2 or 12. Flipping coins follows a binomial distribution B(n, 0.5).
