draw resource allocation graph and analyze state for each process

are Some resource There are six classes of allocatable resouce labelled R1 through R6 There are five processes labelled P1 through P5 There are two instances of each resource There instances already allocated to processes, as follows: One instance of R1 held by Pi, another held by P2 One instance of R2 held by P3 One instance of R3 held by P3, another held by P4 One instance of R4 held by P3 One instance of R5 held by P3, another held by P4 Two instance of R6 held by P5 Some processes have requested additional resources, as follow: P1 wants one instance of R4 P2 wants one instance of R1 and one instance of R2 P3 wants one instance of R1 P4 wants one instance of R6 P5 wants one instance of R3
