A) For the system M/M/. with a finite source N of customers, show that the steady state probability distribution of customers is: N-K ( X ) ( + W B) Answer the following (Prove your answer): 1) For the same p, an M/M/1 is always better with respect to L than an M/M/2. 2) An M/M/2 is always better in terms of system time, than two independent M/M/1 queues with the same service rate but each getting half of the arrivals
