Assignment 1: M/M/1 Performance Evaluation

Assignment 1: M/M/1 Performance Evaluation. Example: The arrival rate to a GAP store is 6 customers per hour and has Poisson distribution. The service time is 5 min per customer and has exponential distribution. On average how many customers are in the waiting line?
