Coordinates of the level random vector (X, Y) are random variables whose common distribution is determined by probabilities
P (X = 6, Y = 9) = 0.3,
P (X = 6, Y = −5) = 0.4,
P (X = 5, Y = -5) = 0.3.
Calculate:

and standard deviation
(b) The expected value of Y
and standard deviation
(c) the expected value of the input XY
(d) correlation between X and Y
