how can i solve this q , as possible as can please

Suppose that X and ) are random variables with outcomes I = 1, 2, and y = 0, 1, 2, with the (incomplete) joint probability distribution P(X = r, Y = y) given in Table 1. Y 0 1 2 X 1/6 1/16 1/8 1/8 Table 1: Incomplete joint probability distribution P(X = x, Y = y) for Problem 1, missing the values P(X = 1, Y = 2) and P(X = 2, Y = 0). (a.) (1 mark) Suppose that P(X = 1) = 13/48. Complete the joint probability distribution in Table 1, i.e. compute P(X = 2, Y = 0) and P(X = 1, Y = 2). (b.) (1 mark) Compute the marginal distribution of Y, i.e. P(Y = y) for y = 0, 1, 2. (c.) (1 mark) Compute the expected value of X, i.e. Ax = E(X). (d.) (1 mark) Compute the variance of X, ie. of - V(X). (e.) (1 mark) Compute P(X 1)
