Messages arrive at an electronic mail server according to a Poisson process with the average frequency of 5 messages per minute. The server can process only one message at a time, and messages are processed on a first come first serve basis. It takes an Exponential amount of time U to process any text message, plus an Exponential amount of time V , independent of U, to process attachments (if there are any), with E(U) = 2 seconds and E(V ) = 7 seconds. Forty percent of messages contain attachments. Estimate 202 Probability and Statistics for Computer Scientists the expected response time of this server by the Monte Carlo method. (Notice that because of the attachments, the overall service time is not Exponential, so the system is not M/M/1.). Please find solution matlab!
