In the game of roulette, a player can place aR$5 bet on the number 25 and have a 1/38 probability of winning. If the metal ball lands on 25, the player gets to keep theR$5 paid to play the game and the player is awarded in additionalR$175. Otherwise, the player is awarded nothing and the casino takes the playerR$5.

Say a single-number bet has a 35:1 payout, and you betR$1. If you win, you'll get your money back plusR$35. Another example: If you win aR$100 bet (for a 35:1 payout), you get a total of $3,600 ($3,500 profit plus theR$100 you initially bet).
