Betting odds work by showing punters the implied probability of an event occurring. Betting odds are simply a method that bookmakers use to describe how much chance of winning a particular bet has. By the end of this piece, hopefully, you will understand betting odds considerably better than before, so you are confident using them with your bookmaker and on betting exchanges.
But don’t forget, betting responsibly is crucial. The more you know, the better you can spot odds converter value bets. For example, if you think Team A has a 50% chance of winning, but the odds give them a 40% chance, you’ve found value. Value betting is like finding a hidden treasure in the world of rugby betting. Ever wondered how bookmakers come up with those odds? You can often find better odds for the same bet.
At the core of sports betting odds lies probability, which is the likelihood of a particular outcome occurring. When using a sports betting odds calculator, you could be using odds in different formats. Being able to switch from fractional odds into decimal odds is another useful ability that will help you to develop your overall betting awareness.
Betting odds are not just a useful tool to help you calculate your winnings, they are a powerful weapon in the ongoing battle to beat the bookmakers. But if you discover that your 3/1 bets are winning more often, that could indicate that you have found a way to uncover value. All things being equal, you would expect that bets made at 3/1 would win around a quarter of the time. This means that you must consistently make bets at odds that are bigger than they should be. Perhaps you will find that you are actually doing well with bets that are odds-on but more poorly with outsiders, suggesting that you find it harder to accurately weigh up the chances of bigger priced options.

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.

The confidence level is the probability that the margin of error (dictated by the relative precision) contains the true odds ratio. The above sample size calculator provides you with the recommended number of samples required to estimate the true odds ratio with the required relative precision and confidence level.

Other odds systems are used more commonly in other parts of the world too. Conversely, if a selection is not attracting as much money as the others, or is attracting very little money, then the bookmaker may increase the value of the odds on that selection. This is called shortening the odds or the odds are said to “come in”. When a selection in a market is backed, the bookmaker will adjust the odds on that selection to a lower price.
