What is the probability that there will be more than six students in the cafeteria or in the queue?
Question 3
[Soalan 31
Jeruk Pak Abu's Store in Butterworth, Pulau Pinang, maintains a successful
catalog sales department in which a clerk takes orders by telephone. If the clerk is
occupied on one line, incoming phone calls to the catalog department are
answered automatically by a recording machine and asked to wait. As soon as the
clerk is free, the party who has waited the longest is transferred and serviced first.
Calls come in at a rate of about 12 per hour. The clerk can take an order in an
average of 4 minutes. Calls tend to follow a Poisson distribution, and service
times tend to be negative exponential. The cost of the clerk is RM10 per hour, but
because of lost good -will and sales, Jeruk Pak Abu's Store loses about RM25 per
hour of customer time spent waiting for the clerk to take an order.
