An operating system uses the Banker's algorithm for deadlock avoidance when managing the allocation of three resource types X, Y, and Z to three processes P0, P1, and P2. The table given below presents the current system state. There are 3 instances of type X, 2 instances of type Y and 2 instances of type Z still available. The system is currently in a safe state. Answer Allocation Маx X Y ZX Y Z PO 0 the following questions! 3 (a) If PO requests 2 instances of Z during the 1 8 4 P1 3 6 2 current state, can it be granted? Explain! (b) If P1 requests 2 instances of X during the P2 2 1 1 3 3 3 current state, can it be granted? Explain!
