Let the random variable and have the joint pmf X Y f(x,y) =
{x(y)^2}/c
where x = 1, 2, 3 ; y = 1, 2, x+y<= 4, that is (x,y) are {(1,1),
(1,2), (2,1), (2,2), 3,1)}
(a) Find . c > 0
(b) Find . μX
(c) Find . μY
(d) Find . σ2 X
(e) Find . σ2 Y
(f) Find Cov . (X,Y )
(g) Find p , Corr . (x,y)
(h) Are and X and Y independent
