The case where the players have the lowest possible probability of both getting a hit.
When two baseball players bat in the same inning, the first gets a hit 25% of the time and the second gets a hit 35% of the time. In each of the following cases, find the covariance, assuming that a hit is worth l point and that a miss is worth 0. (Let P1 be a random variable for the first player and P2 be a random variable for the second player; let P1 = 1 mean that player 1 got a hit, and so forth.) Say why the covariance is positive or negative.
