On Monday mornings, a CIBC branch has only one teller window open for deposits and withdrawals. Experience has shown that the average number of arriving customers in a 4- minute interval on Monday morning is 2.8, and each teller can serve more than that number efficiently. The random arrivals at this bank on Monday mornings are Poisson distributed. (a) What is the probability that on a Monday morning exactly 6 customers will arrive in a 4-minute interval? (b) Suppose the teller can serve no more than four customers in any 4-minute interval at this window on a Monday morning. What is the probability that, during any given 4-minute interval, the teller will be unable to meet the demand? (c) What is the probability that exactly three people will arrive at the bank during a 2-minute period on Monday morning to make a deposit or a withdrawal? (d) What is the probability that five or more customers will arrive during an 8-minute period?
