The following processes are being scheduled using a preemptive, roundrobin scheduling algorithm. Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. In addition to the processes listed below, the system also has an idle task (which consumes no CPU resources and is identified as I ). This task has priority 0 and is scheduled whenever the system has no other available processes to run. The length of a time quantum is 5 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. Enter the times for the above chart starting with 0?

C. What is the turnaround time for each process?

D. What is the waiting time for each process?

E. What is the CPU utilization rate?

Round of to two decimal places.

Please give me the correct answer to each A,B,C,D, and according to the chart and question. Address all the answers by each question please?
