6. Suppose that we are observing the arrivals of customers to a bank every minute for 1 hour. Suppose that all the arrivals are independent, and the probability of having an arrival during each minute is 1/12, the probability of no arrivals during each minute is 11/12. (a) Find the probability of having 2 arrived customers in 1 hour. P.5 of 7 (b) Make use of Poisson distribution to approximate your result in (a). Remark: For answers to both (a) and (b), numerical values are NOT needed. (8 Points)
