Question

Random variables X and Y have the following joint probabilities:P(X=0, Y=0) = P(X= 0, Y=8) = P(X=16, Y=0) = P(X=16, Y=16) = ¼

a)Make a table of the joint distribution of X and Y and add their marginal distributions to the table.

b)Compute Cov(X, Y). Are X and Y positively correlated, negative correlated,or uncorrelated?

c)Compute the correlation coefficient between X and Y.
