jobs arrive to a single server according to a Poisson process with rate 3 per hour. Service times are exponentially distributed with mean 1/ hours. (a) Find so that the steady-state probability that there is more than 1 customer in the system is .25. (b) Now assume that = 5. The server gets a bonus of $1 per job that does not have to wait in the queue before entering service. Calculate the expected bonus per hour that the server makes.
