Consider an M / M / 1 queueing system with capacity N = 1, arrival rate λ = 0.2 customers per minute, and service rate µ =0.3 customers per minute. Let X(t) be the number of customers present at time t.
a) Suppose that X(0) =0. Calculate P{X(1) = 0} and P{X(10) = 0}
b) Suppose that X(0) =1. Calculate P{X(1) = 0} and P{X(10) = 0}
c) Could you have predicted the difference between the answers in part a, and part b by the general theory of limiting probabilities?
