Process Burst Time Priority Arrival
p1 8 15 0
p2 3 20 0
p3 4 20 20
p4 4 20 25
p5 5 5 45
p6 5 15 55

The following processes are being scheduled using a preemptive, priority-based, round-robin scheduling algorithm.

Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. The scheduler will execute the highest-priority process. For processes with the same priority, a round-robin scheduler will be used with a time quantum of 10 units. If a process is preempted by a higher-priority process, the preempted process is placed at the end of the queue.

a. Show the scheduling order of the processes using a Gantt chart.

b. What is the turnaround time for each process?

c. What is the waiting time for each process?

d. What is the average waiting time?
