The goal of making money in betting is to try and find bets where there is value. You should always convert odds into their Implied Probabilities so that you can determine whether or not you feel the payout from a bet is worth it. You need to find bets where you have a margin over the Bookies odds. When a Bookie sets the odds on a bet, he must first determine what chance he gives that bet of winning. This process is called “capping.” The Bookie must work out the probability that he believes a bet will win.

In most cases this means that the arb will get decreased or disappear by the time you see this page are ready to bet. Most sports arbitrage software offer part of their services for free. If you are lucky you’ll be able to find arbitrage opportunity by sorting out the odds by size.

Yes, the return on the higher odds is greater, but doesn’t necessarily represent the better value. Essentially, you are identifying where you think the odds are too high based on your own perception. Expected Value is a measure of how much a bettor should expect to win or lose per bet placed on the same odds time and time again.

So on average, every time we don’t pay our parking ticket we will stand to lose $1.5.

## What It Looks Like To Place A Bet With Positive Expected Value

Similarly, larger sample sizes result in narrower intervals, since the interval’s asymptotic behavior is to be reduced to a single point. This is the equation used in our odds ratio calculator. So a smoker will have 25 higher odds to develop lung cancer compared to a non-smoker. The odds ratio should not be confused with relative risk or hazard ratios which might be close in certain cases, but are completely different measures. Use this odds ratio calculator to easily calculate the ratio of odds, confidence intervals and p-values for the odds ratio between an exposed and control group. One and two-sided confidence intervals are reported, as well as Z-scores.

With this information we can estimate what the standard deviation in the average price ratio of a sample of 1,214 would be. This is to say, if we had a large number of 1,214-bet samples with odds like the ones in my population here, we want to know the standard deviation in the average price ratio across those samples. To investigate how and why a bettor can be beating the closing price like this, we should start by estimating the likelihood of it happening by chance.

Virtus.Pro are playing against Cloud9, and are paying $1.30 to win, while Cloud9 are paying $2.12. Here, a bet of $10 on Virtus.Pro would have a potential winning of $3 ($13 in total winnings, but $10 of your stake), while Cloud9 would be $11.20 ($21.20 in total winnings, but $10 of your stake).
