Implied probability is a formula used to determine if the risk is worth the reward. In other words, the value of your wager. This is fundamental to winning money.
Implied Probability Formula:
- Negative numbers = Favourite
-Odd / (-Odds + 100) * 100 = implied probability - Positive numbers = Underdog
100 / (+Odds + 100) * 100 = implied probability
How to apply the implied probability formula
When checking the lines you find that Fighter A is -450, and Fighter B is +250.
A: 450 ➗ (450 + 100) x 100 = 81%
B: 100 ➗ (250 + 100) x 100 = 28.5%
