For the five processes in the above, we consider RR$-3($Round$-$Robin with Quantum Size $3)$ scheduling policy.

$-$ Draw the Gantt Chart

$-$ Determine the corresponding latency for each process:

$-$ In the following, we consider the context switches, which were ignored in the above. We assume that each context switch takes $0\mathrm{.}2$

time units $($please ignore the switches between the same process$).$ What is the CPU utilization in completing all five processes $($keep three

decimal values$)?$
