QUESTION 4
Assume that the UCC cafeteria has a single cashier. During peak hours, students arrive at a rate of 20 per hour. The average number of students that can be serviced by the cashier is 24 per hour. Calculate the following:
The number of students in the cafeteria
Number of students actively in the queue being served
Waiting time in the cafeteria
Waiting time for students in the queue
What is the probability that there will be more than six students in the cafeteria or in the queue?
Question 3) Waiting Line Analysis
Helen runs a small shop where she provides a service. She is able to process an average of 8 customers per hour. An average of 5 customers per hour seek this service at her shop. What is:
a) the probability that Helen will not be working with a customer (no customers) when the shop phone rings?
b) the probability of 4 customers in the system?
c) the average time a customer spends waiting in line (in minutes)?
