A population has N units, K successes and N-K failures. Choose an unordered simple random sample of n without replacement. X counts sampled successes. Its mass is C(K,x)C(N-K,n-x)/C(N,n). Support is max(0,n-(N-K)) through min(n,K). Draws are dependent because composition changes. The success label is simply the category being counted.
