need help with this joint probability and covariance homework question.. thank you!

6. Suppose that the joint pmf 13(95, 3/) of two random variables X and Y is as follows: 1 0.1 0.1 0.1 y 2 0.1 0.1 0.1 3 0.1 0.1 0.2 (a) (4 points) Find the marginal pmf of X and Y respectively. Do they have the same marginal distribution? Just for this part7 you don't have to 8110\"! work. (b) (3 points) Find P(X = Y). (c) (5 points) What is the conditional pmf of Y given X = 1? (d) (5 points) Find the covariance of X and Y
