Consider the joint probability distribution below. Complete parts (a) through (c). X CF. 1 2 Y 0 0.20 0.15 1 0.55 0.10 C: a. Compute the marginal probability distributions for X and Y. + 4%!) Y 0 0.20 0.15 D 1 0.55 0.10 D PM D E (Type integers or decimals.) b. Compute the covariance and correlation for X and Y. Cov(X,Y) = D (Round to four decimal places as needed.) Corr(X,Y) = D (Round to three decimal places as needed.) c. Compute the mean and variance for the linear function W = X + Y. pw = D (Round to two decimal places as needed.) GEN = D (Round to four decimal places as needed.)
