Balking refers to the refusal of an arriving customer to enter the queue. Reneging refers to the departure of a customer in the queue before obtaining service. Consider an M/M11 system with reneging such that the probability that a specified single customer in line will depart prior to service in a short time interval
 is the number of customers in the system. (Note that ro = r₁, = 0.) Assume Poisson arrivals at rate A and exponential service times with parameter µ, and determine the stationary distribution when it exists.
