Q: By considering the following resource allocation graph.

P = {P1,P2,P3,P4}
R = {R1,R2,R3}
E = {R1 --> P1, P1 --> R2, R2 --> P2, P2 --> R3,
R3 --> P3, P3 --> R1, R1 --> P4}

Case1
- resource type A has two
instances
- resource type B has one
instance
- resource type C has four
instance

Case2
- resource type A has five
instances
- resource type B has two
instance
- resource type C has four
instance

Case3
- resource type A has five
instances
- resource type B has three
instance
- resource type C has three
instance
