In practice, this means that while No Vig odds provide a more accurate reflection of probability, they may still skew slightly over-pricing favourites and under-pricing outsiders. This bias refers to the tendency for bookmakers to offer poorer prices on longshots over favourites compared to their real chance of winning. To use it, input the real odds for each selection, and the calculator will show the No Vig odds and the implied probabilities, ensuring that the total book percentage is always 100%. The No Vig Calculator helps bettors determine the “fair” or “true” odds for a set of selections by removing the bookmaker’s margin (vig). It is not commonly used nowadays, as most bookmakers’ odds are computerised, but it uses a series of gestures of the hands and arms to signify the odds of certain runners in the race.

Specific Bet Type Calculators

For example, if you saw odds of -110 on the New York Knicks to cover the point spread against the Chicago Bulls, you would need to bet $110 to earn a $100 profit.

It can be useful to calculate the probability of a bet landing before parting with your hard-earned cash or free bets. Let’s look at an example of probability in football betting. When researching your bets and revising the gambling industry, it won’t be long before you encounter probability. Betting on Team A in this scenario is a smart move because you’re getting better odds than the actual probability. If you believe a team has a better chance of winning than the odds suggest, that’s a value bet. If your own research suggests a higher probability, you might have found a good betting opportunity.

You can make these types of calculation to assess the % chance you think your selection has of achieving the result you are betting on and see if you feel the odds are giving you enough value to make the bet. The concept of implied probability is worth keeping in mind when you try to assess the value of odds from a bookmaker. With any negative moneyline figure beyond -100 the price is odds against and you stand to make less profit than the stake amount. Again, if the moneyline figure is positive it tells you what you can win on a successful bet with a £100 stake.

• For instance, if you see odds of 2.50 on Team A, and you bet £10 on them, you’d win £25 if they win.

The following data represent a retrospective investigation of smoking in relation to oral cancer. Odds ratio is the key statistic for most case-control studies. In retrospective studies you select subjects by outcome and look back to see if they have a characteristic factor such as a risk factor or a protection factor for a disease. If you need information on prospective studies see risk (prospective). You can examine the likelihood of an outcome such as disease in relation to an exposure such as a suspected risk or protection factor.
