What is the total number of instances under each resource type in this system?
What is the content of the Need matrix?
Is the system in a safe state? If so, show one of the safe sequences. Explain your answer.
From a given snapshot, if a resource-request (0,5,2,0) from P1 arrives (notice that this request is only a subset of what P1 will eventually need to complete its task), should this request be granted at this time? Will the system remain in a safe state? Justify your answer.
