This question and the next two questions are based on the following data: Suppose that we have the following: TOTAL RESOURCES A B C 5 12 7 MAXIMUM CURRENT ALLOCATION A B C A B C P1 3 10 3 1 5 1 P2 2 4 2 0 2 1 P3 2 3 3 2 1 0 P4 2 8 5 1 2 2 Apply Banker's Algorithm: Is the system in a safe state? If Yes, prove by finding a safe sequence while showing the work. If No, explain why. Note: Show the need column. Show the resources available with the system before (and during) when each subsequent process in the safe sequence (if it exists) is executed. This means show the work in the table, as demonstrated in class. Upload the picture of the table.

b.Start from the resource allocation state in Q 13. If a request from a process P3 arrives for (1, 2, 3), can the request be immediately granted ? Why or why not ?
c.Start from the resource allocation state in Q 13. Suppose that P4 asks for 2 instances of resource B. Can the system grant this if it wants to avoid deadlock ? Explain.

Apply Banker's Algorithm: Is the system in a safe state? If Yes, prove by finding a safe sequence
while showing the work. If No, explain why.
Note: Show the need column. Show the resources available with the system before (and during)
when each subsequent process in the safe sequence (if it exists) is executed. This means show the
work in the table, as demonstrated in class. Upload the picture of the table.
