Need help with this problem:

(6) The joint mass function for random variables X and Y is in the following table: p(x,y) =2 X=4 X=6 Y:1 Y=3 0.08 0.18 0.08 Y:5 0.12 0.08 0.24 (a) (1) Compute the marginal mass functions 1);; (a3) and py (y) (b) {1.5) Compute E[X) and V(X) (c) (1.5) Compute E(Y) and V(Y) (cl) (1) Compute E(X Y) (e) (1) Compute C0v(X, Y), and Corr(X, Y)
