Exercise 3. Four servers (S1, S2, S3, and SA) with exponential service time and same service rate fi are busy completing service of four jobs at time t = 0. Jobs depart from their respective server as soon as their service completes. A) Compute the expected departure time of the winning job (the job that completes service first), i.e., tı > 0 [pt. 10). B) Compute the expected departure time of the job that completes service second , i.e., t2 > 1 [pt. 10). C) Compute the expected departure time of the job that completes service third , i.e., ts > t2 [pt. 10). D) Compute the expected departure time of the job that completes service last, i.e., ts > t3 (pt. 10).
