Calculate the average response time for these processes with a nonpreemptive priority Scheduling algorithm? Priority of the process are as follows and consider that all the processes came at zero (0) time. (Note low numbers represent high priority).

Process Arrival Time Burst Time

P1 5 3

P2 3 1

P3 2 5

P4 3 4

P5 1 2

Process Table:

Average response time = \(\frac{{12 + 6 + 2 + 8 + 0}}{5} = 5.6\) ms

Answer: The correct option is 1) 5.6 ms.
