There are two servers available to process n jobs. Initially, each server begins work
on a job. Whenever a server completes work on a job, that job leaves the system and
the server begins processing a new job (provided there are still jobs waiting to be
processed). Let T denote the time until all jobs have been processed. If the time that
it takes server i to process a job is exponentially distributed with rate μi , i = 1, 2,
find E[T] and Var(T).
