Processes P1, P2, and P2 are queued to run. The arrival time of P1 is t = 0, the arrival time of P2 is t = 1, and the arrival time of P3 is t = 2. According to the first come first serve (FCFS) algorithm, processes are run by the operating system. P1 operates 7 time units, P2 4 time units, P3 operates 1 time unit. So what is the average waiting time (in time units) for this system? 0 5 3 7
