All show use of fractional odds: replace (fractional odds + 1) by decimal odds if decimal odds are known. Non-runners are treated as winners with fractional odds of zero (decimal odds of 1). Fractions of pence in total winnings are invariably rounded down by bookmakers to the nearest penny below. Calculations below for multiple-bet wagers ...
The numerator and denominator of fractional odds are often integers, thus if the bookmaker's payout was to be £1.25 for every £1 stake, this would be equivalent to £5 for every £4 staked, and the odds would therefore be expressed as 5/4. However, not all fractional odds are traditionally read using the lowest common denominator. For example ...
The term "fractional odds" is something of a misnomer, especially when visually reinforced by using a slash (as opposed to, e.g., a colon or the word "to" or "on") to separate a potential gain from the amount that a bettor must wager in order to receive it upon a win, because the "fraction" in question represents not the odds of winning or even ...
Example of the optimal Kelly betting fraction, versus expected return of other fractional bets. In probability theory, the Kelly criterion (or Kelly strategy or Kelly bet) is a formula for sizing a sequence of bets by maximizing the long-term expected value of the logarithm of wealth, which is equivalent to maximizing the long-term expected geometric growth rate.

The values given for Probability, Cumulative probability, and Odds are rounded off for simplicity; the Distinct hands and Frequency values are exact. The nCr function on most scientific calculators can be used to calculate hand frequencies; entering nCr with 52 and 5 , for example, yields ( 52 5 ) = 2 , 598 , 960 {\textstyle {52 \choose 5 ...
Finally, there's good news for homebuyers and for homeowners who want to refinance their mortgages: The 30-year fixed mortgage rate now averages 6.73%, dropping significantly from its 20-year peak ...
