(There are 18 red compartments, 18 black compartments, and 2 compartments that are neither red nor black.) If the ball lands on red, you get to keep the $14 you paid to play the game, and you are awarded $15. If the ball lands elsewhere, you are awarded nothing, and the $14 that you bet is collected. Write down the probability distribution for the earnings from this type of bet and find the expected value. Give the probability distribution.
