Let X and Y have the joint probability distribution function fx,y(x,y)= 6y, if 0
Given X,Y having the joint probability mass function p(x,y) from the table:
(x,y) = (0,0) (0,1) (0,2) (1,1) (1,2) (2,2)
p(x,y)= 1/12 2/12 1/12 3/12 4/12 1/12
find px(x), py(y), mu(x), mu(y), row(x)^2, row(y)^2, e(X,Y).
