In the table below, you are given 3 processes including their arrival time and burst time (in seconds):

1- By using Round Robin Algorithm, show how the algorithm will schedule the processes using the Gantt chart. The time quantum (q) = 4.

2- Calculate the waiting time for each process. 3- Compute the average waiting time.

\begin{tabular}{|l|l|l|} \hline Process-ID & Arrival time & Burst Time \\ \hline P1 & 0 & 9 \\ \hline P2 & 0 & 6 \\ \hline P3 & 0 & 3 \\ \hline \end{tabular}
