No, Seriously

Honestly, I have one question left on my homework, anyone out there want to take a stab at guiding me through it? If it works I will say wonderful things about you :)

Suppose X and Y have the following joint distribution:
(a) Find the covariance of X and Y, i.e. Cov(X,Y).
(b) Find the correlation of X and Y, i.e. ρ(X,Y).
(c) Are X and Y independent variables?

Did you ever solve this? I am in the trenches with the same exact problem for my FIN homework and am absolutely stumped!
