Fractional odds like 1/2 can seem confusing at first, but the decimal version makes it easier to understand. Decimal odds quickly show you the potential return on your bet, making it easy to see if a bet is worth placing. By the end, you’ll know how to read them and use them to make informed betting choices.

A 1/4 (1.25 or -400) bet would be expected to be successful in four of every five attempts, it is heavily ‘odds on’ and the implied probability is 80%.

They suggest a probability of around 32%, and you’ll often find them when there’s no clear favourite – especially in sports like football, tennis, or racing. The odds will be expressed as a decimal though – 3.10. 21/10 means you get £21 back in profit for every £10 staked, while 2/1 gives you £20.

We consider here what the odds of aspiring to remain in FTE are separately for boys and girls, i.e. conditional on gender. The above are the unconditional odds, i.e. the odds in the sample as a whole. The odds tell us that if we choose a student at random from the sample they are 4.43 times more likely to aspire to continue in FTE than not to aspire to continue in FTE. However another way of thinking of this is in terms of the odds. This is equivalent to saying that the probability of aspiring to continue in FTE in our sample is 0.816. The mean of the variable will equal the proportion of cases with the value 1 and can therefore be interpreted as a probability.

Fractional Odds

In this post, we are going to explain a number of important things to note about odds. Our odds converter works automatically and in an instant, so you can quickly get the odds that you need. All that you need to do is input the odds that you need converting into the relevant box – such as +400 odds into the American odds box – and then read the results of the other boxes. You can much more easily convert any odds you want with our useful and quick tool. Of course, with the Paddy Power odds converter, you don’t need to run these sums. Then, the PP odds converter will automatically convert it into all of the other main types of odds.

• All that you need to do is input the odds that you read into its relevant box.
• What ever type of bet you would like to place, from accumulators to Super Yankees, we have you covered!
• This is calculated as 100 divided by the probability of 20%.
• Bookmakers use odds as a way of showing the chance/probability of a certain outcome happening, with the lower the odds, the more chance of the outcome occurring.
• The advances in AI, computing power and processing speed mean it is now possible for bookmakers to offer odds on markets within a fraction of a second, or to update markets in real time (which is what happens in In Play betting).

This asymmetry is unappealing because ideally the odds for males would be the opposite of the odds for females. As we saw in our example above, an OR of 2.0 indicates the same relative ratio as an OR of 0.50, an OR of 3.0 indicates the same relative ratio as an OR of 0.33, an OR of 4.0 indicates the same relative ratio as an OR of 0.25 and so on. So another way of looking at this is that the odds for each gender can be expressed as a constant multiplied by a gender specific multiplicative factor (namely the OR). Extension D provides a table that shows the equivalence between ORs in the range 0 to 1 with those in the range 1 to infinity. Note that the way odd-ratios are expressed depends on the baseline or comparison category. If however the odds differ then the OR will depart from 1.
