Assume the following set of processes, with the length of the CPU burst time given in milliseconds. The processes P1, P2, P3, P4, P5 have arrived at different times. Process Burst-Time Arrival-Time P1 8 0 P2 3 3 P3 10 4 P4 9 6 P5 7 11 Which of the following display the correct wait time of these processes using the FCFS scheduling algorithms? Hint: You might need to draw the Gantt charts to answer this questions
