Given the three processes p1, p2 and p3.
Their execution time are respectively estimated at X, Y and Z such that X < Y < Z.
To run these processes we have the choice between the two following schedules:
(1) p1, p2, p3,
(2) p2, p1, p3.
What is the best scheduling compared to the average response time?

Given the following Schedule of Three processes P1,P2 and P3 : 

P1----> P2 -----> P3

Knowing that the processes arrived the same time (0ms) and the execution time for them is X,Y,Z respectively .

What is the response time for each of the three processes: 

a. P1=0, P2 = X , P3 = X+Y

b. P1 = X , P2 = Y , P3 = X+Y+Z

c. P1 = 0 , P2 = X+Y , P3 = X+Y+Z

d. None of the above
