The 3/2 plan is a bet on both bets at once. Three chips are placed on Red, Black, Odd or Even, and two chips are placed on one of the three columns. The theory is that enough numbers are covered in one spin to give the player a chance to make a profit.

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.
