Betting Accumulator Calculator

[Ace123]

How do you calculate the odds if you want to do a treble bet? i know there are calculators to do this for you on the net but i want to know the actual calculation behind this. for eg, if the odds for home wins for 3 matches are 1.83, 2.5 and 2. and you want to bet on all home wins the calculator spits out an overall odds of 9.15. I want to know how 9.15 is derived. Thanks in advance

Re: Betting Accumulator Calculator Just multiply together the individual odds: 1.83 x 2.5 x 2 = 9.15
