Two books are randomly selected without substitution from a shelf where there are four copies of statistics, three of mathematics, and four of finance. If x is the number of statistics books and Y is the number of mathematics volumes selected, construct a table showing the values of the joint probability distribution of X and Y, to calculate: (a) the expected value of g( X, Y) = 3X-y. Also, (b) the covariance and correlation coefficient of X and Y.
