How It Works
The hypergeometric distribution models drawing cards without replacement from a finite deck. Unlike binomial probability, it accounts for the changing composition of your library as you draw.
The formula: P(X=k) = C(K,k) * C(N-K, n-k) / C(N,n)
Where N = deck size, K = copies in deck, n = cards drawn, k = successes.
