5) X and Y are jointly continuous with joint pdf ( , ) = ≤ , ≤
a- Verify that the f(x, y) is a joint probability density function
b- Find the marginal mass function of x
c- Find the marginal mass function of y
d- Are X and y independent (Why)
e- Find E(X) and find E(Y)
f- conditional expectation of Y given X = x

i think it is c, not positive though
