Gambling provides some people a rush and a return on their bet if they win. The odds of winning a game depend on many variables, such as who is the starting pitcher or is anyone injured. Generally, the bookie will provide a money line and this money line shows how much the gambler will collect if he wins his bet.

## Instructions

- 1
Find the money line for the event (see Resources). For example, a gambler wants to bet on a baseball game. The money line for the game is -125.

- 2
Add 100 to the money line then divide by the money line if betting on the favourite. This number is the factor for the favourite. In this example, 125 plus 100 equals 225. Then, 225 divided by 125 equals 1.8.

- 3
Add 100 to the money line then divide by 100 to determine the factor for the underdog. In this example, 125 plus 100 equals 225. Then 225 divided by 100 equals 2.25.

- 4
Multiply the factor by the bet. Then subtract the initial bet. In this example, if the gambler bet £65 on the underdog, he will win £81: £65 times 2.25, which equals £146, then subtract the initial bet of £65. If the gambler bet on the favourite, then £65 times 1.8 equals £117. Then, £117 minus £65 equals £52.
