In proof testing of circuit boards, the
Chapter 3, Problem 88(choose chapter or problem)
In proof testing of circuit boards, the probability that anyparticular diode will fail is .01. Suppose a circuit boardcontains 200 diodes.a. How many diodes would you expect to fail, and whatis the standard deviation of the number that areexpected to fail?b. What is the (approximate) probability that at leastfour diodes will fail on a randomly selected board?c. If five boards are shipped to a particular customer, howlikely is it that at least four of them will work properly?(A board works properly only if all its diodeswork.)
