SenQ Mail Order Company provides free examination of its products for seven days. If not completely satisfied, a customer can return the product within the period and get a full refund. According to past records of the company, an average of 1 out of every 20 products sold by this company are returned for a refund. (a) 29. Using binomial distribution, find the probability that exactly 4 of the 60 products sold by this company on a given day will be returned for refund. By using Poisson distribution as an approximation, find the probability for the case in (a). Is the Poisson distribution a good approximation for the binomial distribution? Comment. (b)
