Suppose you work at a bank, and on average, you receive 12 requests for a mortgage consultation per day. What is the probability that you will receive exactly 12 mortgage consultation requests tomorrow? What is the probability that you will receive no more than 10 mortgage consultation requests tomorrow? What is the mean and variance of the number of mortgage consultation requests on any given day? If you want to ensure a 95% chance of having enough staff to handle the daily mortgage consultation requests, how many employees should you have available each day, assuming each employee can handle one consultation per hour, and the bank is open for 8 hours each day?
