Figuring it out involves converting odds into a percentage, which indicates the likelihood that event will happen vs. the alternative. Therefore, if you wager $40 on Ottawa, you will win $44.00, and your total payout would be $84.00.

In this example, the negative number indicates the favorite, while the positive number indicates the underdog.
