b. In proof testing of circuit boards, the probability that any particular diode will fail is 0.01. Suppose a circuit board contains 200 diodes. I. How many diodes would you expect to fail, and what is the standard deviation of the number that are expected to fail. II. What is the probability that at least four diodes will fail on a randomly selected board. III. If six boards are shipped to a particular customer, what is the probability that at least four of them will work properly.
