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 $7 on red?
Round your answer to two decimal places.
