    Assume a system with 3 processes P1, P2, and P3, and resources R1, R2, and R3. Each resource has a single instance. Draw a resource allocation graph for the following sequence of events: P1 is granted access to resource R1. P2 requests resource R1 P3 requests resource R3 P2 is granted access toR2 P1 requests R2 Convert your resource allocation graph to a wait-for graph. Is there a deadlock?

    Please give an explanation for the answers as well. 1. A system has three processes (P1, P2, and P3) and three resources (R1, R2, and R3). There is one instance of RI, two instances of R2, and three instances of R3. PI holds RI and one instance of R3 and is requesting one instance from R2. P2 holds one instance of R3 and is requesting RI and one instance from R2. P3 holds two instances of R2 and one instance...
