(Hint: average the number milliseconds each job was in a wait state) c) Calculate the average turn-around-time (Hint: for each job, count the number of miliseconds from arrival to completion and average
ob 1: arrives at time 0 and needs 500 milliseconds to complete.
Job 2: arrives at time 300 milliseconds and needs 400 milliseconds to complete.
Job 3: arrives at time 400 milliseconds and needs 200 milliseconds to complete.
Job 4: arrives at time 400 milliseconds and needs 500 milliseconds to complete.
