Just need help for question C

4.2-2. Let X and Y have the joint pmf defined by f(0, 0) = f(1, 2) = 0.2, f(0, 1) = f(1, 1) = 0.3. (a) Depict the points and corresponding probabilities on a graph. (b) Give the marginal pmfs in the "margins." (c) Compute ux, MY, 67, 63, Cov(X, Y), and p. (d) Find the equation of the least squares regression line and draw it on your graph. Does the line make sense to you intuitively
