Exam 19: Waiting Line Models

Explore all topics

Consider a single-line, single-server waiting line system. Suppose that customers arrive according to a Poisson distribution at an average rate of 50 per hour, and the average (exponentially distributed) service time is 45 seconds per customer. What is the probability that 4 customers are in the system?
