Need help with how to calculate CPU Utilization and waiting time

Consider two t processes, cach with two CPU bursts withone burst in betwcen. Process I has a CPU burst of 9 units followed by an LO burst of 7 units and a CPU burst of 6 unit. Process 2 has a CPU burst of 2 units followed by an LO burst of 1 units and a CPU burst of 3 units Sappose that Proccss 1 arrives in the ready queue just beforc Process 2 and just after Proocss 2 arnives the process that was in the CPU seminates. No other processes are in the system. For cach of the scheduling algorithms below crcote Gantt charts like you did for assignment 2 Fill cach box with the state of the coresponding process. Use R for running, W for waiting, andr r ready. Calculate the waiting times and CPU utilization (as a fraction)for each process and fl nhe tahle below. a) First-Com/First-Scrved h) Shortest Joh irst (non-preenaptive) c) Preemptive Shortest Job First d) Round Rohin with a quantum of3.
