a) Suppose that X has a hypergeometric distribution with N=130,n=4,K=20. FPC= If finite population correction factor is small a binomial distribution can effectively approximate the hyper Calculate the following probabilities, assuming that X has a binomial distribution. P(Xbin=1)=P(Xbin=4)= Use the binomial approximation to the hypergeometric distribution to approximate the following probabilities. If 21 cards are defective, what is the probability that at least 1 defective card is in the sample? P(X)= If 6 cards are defective, what is the probability that at least 1 defective card appears in the sample? P(X)=
