a)
Summary Introduction
To determine: The Little’s formula applied to the first subsystem.
Introduction: In order to predict the waiting time and length of the queue, queueing model will be framed. Queueing theory is the mathematical model that can be used for the decision-making process regarding the resources required to provide a service.

4.9).
(Do not round intermediate calculations. Round your answer to three decimal places.)
What is the average number of customers in the queue?
customers
In an M/M/1 queueing system, the arrival rate is 7 customers per hour and the service rate is 12 customers per hour. (Round your answers to 3 decimal places)
a. What is the probability that the server will be idle?
b. What is the probability of having exactly 4 customers in the system?
c. What is the probability of having 4 or fewer customers in the system?
suppose tht a queueing system has two identical servers, and an exponential service-time distribution with a mean of 1/u=10minutes. furthermore, a customer has just arrived to find two in the system. how long would you expect him to wait before being able to start service?
