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?0.010X(b) How small should the probability of a defective rivet be to ensure that only 5% of all seams need reworking?

A medical test is available to determine whether a patient has a certain disease. To determine the accuracy of the test, a total of 9700 people are tested. Only 100 of these people have the disease, while the other 9600 are disease free. Of the disease-free people, 9300 get a negative result, and 300 get a positive result. The 100 people with the disease all get positive results. Round your answers to four decimal places, if necessary. Find the probability that the test gives the correct result for a person who does not have the disease.
