An instructor has given a short quiz consisting of two parts. For a randomly selected student, let X = the number of points earned on the first part and Y = the number of points earned on the second part. Suppose that the joint probability distribution of X and Y is given in the accompanying table. Y 0 5 10 15 Px(x) 0 0.02 0.06 0.02 0.10 0.20 5 0.04 0.15 0.20 0.10 0.49 X 10 0.01 0.15 0.14 0.01 0.31 Py(y) 0.07 0.36 0.36 0.21 1.00 Compute the covariance for X and Y.
