A BinomialDistribution gives the probability of obtaining a given number of successes in a given number of drawns from an infinite population with a given fraction of successes an failures. (Equivilently, the infinite-population property is also sometimes expressed as making the draws "with replacement".) A hypergeometric distribution, by way of contrast, gives the probability of obtaining a given number of successes in a given number of draws from a finite population containing fixed numbers of successes and failures. Each of the draws in the binomial case is identical and independent, but in the hypergeometric case the draws are without replacement, so the outcome of previous draws affect the probability of obtaining success or failure in subsequent draws.
