One option in a roulette game is to bet on the color red or black. (There are 18 red compartments, 18 black compartments and two compartments that are neither black nor red.) If you bet on a color you get to keep your bet and win that same amount if the color occurs. If that color does not occur you will lose the amount of money you wagered on that color to appear. What is the expected payback for this game if you bet $6 on red?
