Compare the binomial probability law and the hypergeometric law introduced in Prob- lem 2.54 as follows.
(a) Suppose a lot has 20 items of which five are defective. A batch of ten items is tested without replacement. Find the probability that k are found defective for k = 0, … , 10. Compare this to the binomial probabilities with n = 10 and p = 5/20 = .25.
(b) Repeat but with a lot of 1000 items of which 250 are defective. A batch of ten items is tested without replacement. Find the probability that k are found defective for k = 0, … , 10. Compare this to the binomial probabilities with n = 10 and p = 5/20
= .25.
