A process requires 10 ms of CPU burst time. A Round Robin scheduler uses a time quantum of 4 ms. Assuming the process is not blocked for I/O, how many times will it receive the CPU before completion?
Consider the following processes:
| Process | Arrival Time | Burst Time |
|---|---|---|
| P1 | 0 | 5 |
| P2 | 2 | 3 |
| P3 | 4 | 4 |
| P4 | 6 | 6 |
| P5 | 8 | 2 |
