In the supreme court, two justices, A and B, are required to vote on various matters. Records are kept and enough votes have been seen to approximate the probabilities of various events. In particular, each justice can vote in either a more liberal or more conservative direction. We will encode this measure of liberalism in voting by listing a vote in the conservative direction as 0 and a vote in the liberal direction as 1 for each justice. Hence let X be the liberalism value for the vote by justice A on randomly chosen matter and Y be the liberalism value for vote by justice B on the same matter. The joint distribution of voting tendencies by the two justices, i.e. (X, Y), is given by the following table (X by the row, Y by the column). XITY 0 1 0 0.2 0.15 1 0.15 0.5 What is the covariance between X and Y?
