One option in a roulette game is to bet $ 6

on red. (there are 18 red compartments, 18 black compartments, and two compartments that are neither red nor black.) if the ball lands on red, you get to keep the $ 6

you paid to play the game and you are awarded $ 6
.
if the ball lands elsewhere, you are awarded nothing and the $ 6

that you bet is collected
