Q2. A company producing electric relays has three manufacturing plants producing , 55, 20, and 25 percent, respectively, of its product. Suppose that the probabilities that a relay manufactured by these plants is defective are 0.025, 0.02, and 0.045, respectively. a. If a relay is selected at random from the output of the company, what is the probability that it is defective? b. If a relay selected at random is found to be defective, what is the probability that it was manufactured by plant 3?

A.a.Two electricians are discussing industrial cabling. Electrician A says that copper cable provides clearer transmission signals than fiber optic cable. Electrician B says that fiber optic cables will be larger thancopper cables with identical data transmission rates. Who is correct?B. Both Electrician A and Electrician B are correct.C. Only Electrician A is correct.D. Neither Electrician A nor Electrician B is correct. A.b. Two electricians are discussing industrial cabling. Electrician A says that signal losses in fiber optic cableare more likely to be caused by splices and connectors than cable length. Electrician B says that wire-wrapterminations should be used when there isn't enough time available to use IDC terminations. Who iscorrect?A. Only Electrician A is correct.B. Both Electrician A and Electrician B are correct.C. Only Electrician B is correct.
