A shipment of 15 portable television sets is received by a
retailer. To protect herself against a bad shipment, she will
inspect 4 sets and accept the entire lot if she observes no more
than 1 defective. Suppose that there are actually 6 defective sets
in the shipment.
What is the probability that she accepts the entire
shipment?
What is the type of discrete probability distribution (binomial,
hypergeometric, or
Poisson) that describes this problem? Explain.
