If we sample from a small nite population without replacement, the binomial distribution should not be used because the events are not independent. It sampling is done without replacement and the outcomes belong to one of two types. we can use the hypergeometric distribution. [f a population has A objects of one type, while the remaining B objects are of the other type, and ifn objects are sampled without replacement, then the probability of getting 1 objects oftype A and n )
