1. Calculate the CPU Utilization and Idle time by considering 35% I/O wait and the number of processes is from 1 to 5. Draw a chart as well, where x-axis showing the number of processes and y-axis showing CPU utilization.

You need to calculate 5 processes.

Cpu utilization = 1 - p ^ n

P is I/O wait and n is no. Of processes

So you need to calculate CPU utilization where the value of n =1, n=2 ,n=3,n=4, n = 5.
