What does +120 mean in betting?
+120 means a $100 bet wins $120, and a $10 bet wins $12. The price says it wins 45.5% of the time, so at +120 you make money on bets that win more than 45.5% of the time.
In plain words
+120 is a slight underdog: a $100 bet wins $120, and a $10 bet wins $12.
The price says 45.5%, a little under a coin flip. Because a win pays more than you risk, you can lose more than half of these bets and still come out ahead, as long as you win more than 45.5%.
Its usual partner on the other side is -140. Together they add up to 103.8%; the extra 3.8% is the book's cut.
Where you see +120
