For instance, if you bet $10 at 9/2 odds and your horse wins, then you would receive a payout of $45 ($10 x 9 = $90 $90 – $10 = $45). In this example, 9/2 odds mean that for every $2 you bet, you will win $9 if your horse comes in the first place. Odds are expressed as a ratio of the amount you will win compared to the amount you bet, such as 9/2.
Horse racing odds are the return you can expect on your investment if your wager is successful.
