An aircraft seam requires 30 rivets. The seam will have to be reworked if any of these rivets is defective. Suppose rivets are defective independently of one another, each with the same probability. (Round youranswers to four decimal places.)(a) If 24% of all seams need reworking, what is the probability that a rivet is defective?(b) How small should the probability of a defective rivet be to ensure that only 11% of all seams need reworking?

The number of rivets = 30Probability that no rivets are defective = (1-p)30Probability that at least…
