## How to Convert an Implied Probability to Fractional odds

**To convert an Implied Probability to Fractional odds:**

(Divide 1 by (the percentage divided by 100)) and subtract 1. Example for a 40% implied probability: (1 / (40 / 100)) - 1 = 1.5/1 or 3/2

## Implied Probability and Fractional odds Explained

Here are the basics of implied probabilities and Fractional odds.

### Implied Probability

While sportsbooks don't typically express their odds in implied probabilities, all common odds formats can be converted to an implied probability. An implied probability is the percentage of times you'd need to win a bet (if you could bet it an infinite number of times) for that bet to breakeven.

For example, if your odds convert to an implied probability of 60%, your bet theoretically needs to win 60% of the time to breakeven. If it wins more than 60%, it'd be a profitable bet.

Keep in mind that sportsbooks add vig ("juice", "house edge", "tax", "fees", etc.) to their odds, meaning the implied probabilities of all outcomes for a scenario will have implied probabilities totaling greater than 100%.

### Fractional Odds

Most popular in the United Kingdom and Ireland, fractional odds are expressed as a fraction where the denominator is the amount bet, and the numerator is your potential winnings. For example, if you win a bet placed at 1/3 odds, you'll profit $1 for every $3 bet.

Fraction odds are also commonly used in the United States for horse racing.

- Fractional odds greater than 1 are underdogs, with larger fractions having a lower implied probability. 11/10 has an implied probability of 47.62% and 3/1 is 25%.
- Fractional odds less than 1 are favorites, with smaller fractions having a higher implied probability. 10/11 is an implied probability of 52.38% and 1/3 is 75%.
- 1/1 has an implied probability of exactly 50%.
