Three processes, P1, P2, and P3, arrive at the system as follows: P1 has an arrival time of 0 and a burst time of 8; P2 has an arrival time of 1 and a burst time of 3; P3 has an arrival time of 2 and a burst time of 5. Using the Round Robin (RR) scheduling algorithm with a time quantum of 3 ms, what is the turnaround time for process P2?
