The resource allocation graph is the diagrammatic representation of the state of a system. It denotes the complete information about all the processes which are holding some resources or waiting for some resources.
It also contains the knowledge about all the instances of all the resources whether they are available or being used by the processes. In Resource allocation graph, the process is represented by a Circle while the Resource is represented by a rectangle.
A deadlock happens in operating system when two or more processes need some resource to complete their execution and these resources are held by the other processes.
The principle is that if a resource allocation graph does not have a cycle then the system is not in a deadlock state and if there is cycle then the system may or may not be in a deadlocked state and it depends upon the number of instances of the currently available resources at that time.
For the above diagram mentioned in the question there is a cycle
P1-> R2-> P2-> R1
So process P1 and process P2 are surely in a deadlocked state so second option is correct.
First and third Option none and maybe is incorrect
Regarding last option which is as given yes P1, P2 and P3 are in it ,is also incorrect since there is no cycle in resource allocation graph for processes P1,P2 and P3..

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...

2.8 Deviations from the mean Sometimes it is convenient to write the simple linear regression model in a different form that is a little easier to manip- ulate. Taking Equation (2.1), and adding ßix -P,T, which equals 0, to the right-hand side, and combining terms, we can write (2.24) where we have defined α-A+A. This is called the deviations from the sample mean form for simple regression. 2.8.1 What...
