Post by: assignment009 on Dec 18, 2017 Customers enter the waiting line to pay for food as they leave a cafeteria on a first-come, first-served basis. The arrival rate follows a Poisson distribution, while service times follow an exponential distribution. If the average number of arrivals is four per minute and the average service rate of a single server is seven per minute, on average, how much time will elapse from the time a customer enters the line until he/she leaves the cafeteria?
A) 0.67 minute B) 0.50 minute C) 0.75 minute D) 0.33 minute E) 1.33 minutes Title: Re: Customers enter the waiting line to pay for food as they leave a cafeteria on a first-come, ... Post by: somchaip on Dec 18, 2017 Content hidden
