The number of defective parts produced per shift can be modeled using a random variable that has the Poisson distribution. Assume that, on average, three defective parts per shift are produced. (a) What is the probability that exactly four defective parts are produced in a given shift? (b) What is the probability that more than seven defective parts are produced in the next two shifts? (c) What is the probability that at the most eight defective parts are produced in the next three shifts?
