Assume the system consists of four resources, R1, R2, R3, R4. Before any process runs, there are 3 R1s, 6 R2s, 6 R3s and 5 R4s available. There are also 4 processes. P1, P2, P3, P4. At the time of interest, the state of the program looks like this: Worst Case Need Current allocation Process R1 R2 R3 R4 R1 R2 R3 R4 P1 1 2 2 3 0 2 2 1 P2 1 3 3 1 1 1 1 1 P3 0 3 2 5 0 3 2 1 P4 1 6 1 5 1 0 1 0 a) Show that the system is safe in this state. b) Assume we get a request from P3 for one (1) R4. Is the system still safe? c) What possible requests can be granted without driving the system into an unsafe state?e Windows Settings to activate
