Consider $5$ processes whose Arrival time and CPU Burst time is as follows $($Process no: Arrival time : Burst time$)$:

P$1$ : $0,6$

P$2$ : $1,4$

P$3$ : $5,7$

P$4$ : $6,5$

P$5$ : $7,9$

Assume that the processes are scheduled using FCFS scheduling algorithm.

The average waiting and turaround time?
