An aircraft seam requires 26 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 your answers to four decimal places.) (a) If 24% of all seams need reworking, what is the probability that a rivet is defective? 0.010 X (b) How small should the probability of a defective rivet be to ensure that only 5% of all seams need reworking?
