Question: Customers arrive at a queueing system according to a Poisson
Customers arrive at a queueing system according to a Poisson process with a mean arrival rate of 2 customers per minute. The service time has an exponential distribution with a mean of 1 minute. An unlimited number of servers are available as needed so customers never wait for service to begin. Calculate the steady-state probability that exactly 1 customer is in the system.
Answer to relevant QuestionsSuppose that a single-server queueing system fits all the assumptions of the birth-and-death process except that customers always arrive in pairs.
