Q. 8
You are Given the Following:- A set of Processes P = {P1, P2, P3} ; A set of Resources R = {R1, R2, R3, R4} Resource Instances: One instance of resource type R1; Two instances of resource type R2; One instance of resource type R3; Three instances of resource type R4. Process States: Process P1 is holding an instance of resource type R2 and is waiting for an instance of resource type R1. Process P2 is holding an instance of R1 and an instance of R2 and is waiting for an instance of R3. Process P3 is holding an instance of R3.
