32.5% probability of outcome.

The probability of an event occurring is the likelihood that it will happen, expressed as a fraction or decimal. For example, if the odds of something happening are 13/27, the probability would be 13/(13+27) = 13/40. This means that there is a 13 in 40 chance, or 32.5% probability of outcome., that the event will occur.

If you bet £10 on odds of 13/27 and your bet wins, you would win £4.815. To calculate your winnings, you would multiply your bet amount by the decimal odds and subtract your original bet. In this case, the calculation would be as follows: £10* (13/27 + 1) - £10 = £4.815. Remember that betting involves risking money, so you should only bet what you can afford to lose. BeGambleAware.org
