A customer service desk at a library sees on average 10 customers per hour. a. What is the probability that between 7 and 10 customers come in a given hour? b. The library is open from 10 AM to 4 PM. What is the likelihood that the desk sees no more than 55 customers in one day? c. Assume that each customer takes 3 minutes to serve at the desk. If there is a line of customers at waiting to be helped at 3:45, what is the probability that the library staff member will have to stay past closing?
