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 3 time 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?](https://content.bartleby.com/qna-images/question/72a7e467-409a-435c-b775-dfd6c1ab0b97/63ff7855-2fbd-4356-bdc4-cfbb80c0cd52/bm6js2a_thumbnail.png)
