# How Are True Odds Calculated?

The true odds of an event are the actual probability of it occurring. They are based on the likelihood of something happening, and are expressed as a ratio. They are used to calculate the returns on a bet, and can be used to determine whether a bet is a good one or not. In this article, we will look at how true odds are calculated and how they can be used to make informed betting decisions.

### What Are True Odds?

True odds are the mathematical probability of an event occurring. They are expressed as a ratio and are based on the likelihood of something happening. For example, the true odds of rolling a six on a six-sided die are 1:5. This means that for every five times the die is rolled, it is expected to land on a six one time.

### How Are True Odds Calculated?

True odds are calculated by taking the probability of an event occurring and expressing it as a ratio. To determine the probability of an event occurring, you can use the following formula:

Probability of Event Occurring = Number of Favorable Outcomes / Total Number of Possible Outcomes

For example, the probability of rolling a six on a six-sided die is 1/6 (1 favorable outcome out of 6 possible outcomes). Therefore, the true odds of rolling a six are 1:5 (1 favorable outcome out of 5 possible outcomes).

### What Are Decimal Odds?

Decimal odds are a type of betting odds used in sports betting and casinos. They are expressed as a decimal number and represent the return a bettor will receive if they win their bet.

For example, if the decimal odds of an event are 3.00 then a bettor will receive 3 times their stake if the event occurs. In other words, if the bettor stakes \$1 then they will receive \$3 if the event occurs.

### What Are Fractional Odds?

Fractional odds are another type of betting odds used in sports betting and casinos. They are expressed as a fraction and represent the return a bettor will receive if they win their bet.

For example, if the fractional odds of an event are 3/2 then a bettor will receive 3 times their stake plus 2 times their stake if the event occurs. In other words, if the bettor stakes \$1 then they will receive \$5 if the event occurs.

### How Are Betting Odds Calculated?

Betting odds are calculated by taking the true odds of an event occurring and then adjusting them to create a more attractive betting market. This is done by creating a margin that the bookmaker can use to make a profit.

For example, if the true odds of an event are 1:5 then the bookmaker may adjust them to 2:1 to create a more attractive betting market. This means that a bettor would receive 2 times their stake if the event occurs rather than the true odds of 1 times their stake.

### What Are Implied Odds?

Implied odds are the odds that are implied by the betting markets. They are calculated by taking the betting odds and adjusting them to account for the bookmaker’s margin.

For example, if the betting odds of an event are 2:1 then the implied odds are 1:5. This means that the true odds of the event occurring are 1:5 and the bookmaker has added a margin of 1:4 to create a more attractive betting market.

### What Are Value Bets?

Value bets are bets that offer a higher return than the true odds of an event occurring. They are usually found when the betting odds are higher than the implied odds.

For example, if the betting odds of an event are 4:1 and the implied odds are 1:5 then the bet is offering value. This is because the bettor would receive 4 times their stake if the event occurs rather than the true odds of 1 times their stake.

### How to Calculate Expected Value

Expected value (EV) is a calculation used to determine the likely return of a bet. It is calculated by taking the true odds of an event occurring and then adjusting them to account for the bookmaker’s margin.

For example, if the true odds of an event are 1:5 and the betting odds are 2:1 then the EV is 0.50. This means that a bettor would expect to receive 0.50 times their stake if the event occurs.

### Conclusion

True odds are the mathematical probability of an event occurring and are expressed as a ratio. They are used to calculate the returns on a bet, and can be used to determine whether a bet is a good one or not. Decimal and fractional odds are types of betting odds used in sports betting and casinos, and are adjusted to account for the bookmaker’s margin. Implied odds are the odds that are implied by the betting markets and value bets are bets that offer a higher return than the true odds of an event occurring. Finally, expected value (EV) is a calculation used to determine the likely return of a bet.
