A computer program can make calls to two subroutines, A and B. In a randomly chosen run, let X be the number of calls to subroutine A and let Y denote the number of calls to subroutine B. The joint probability mass function of X and Y is given in the following table.

y
x	1	2	3
1	0.15	0.10	0.10
2	0.10	0.20	0.15
3	0.05	0.05	0.10

a. Find the conditional probability mass function Px|y(y|2)

b. Find the conditional expectation of E(Y|X =2)

c. Find the correlation coefficient between X and Y. (Show all solution steps).
