    Hey all,

    Just wondering if anyone could do me a favour and work out some odds for?

    Basically i'm looking for the odds of 3 numbers coming up in the lotto, including the bonus number.

    Lets just say for arguments sake the numbers are 8, 16, 27

    Cheers in advance

    Think this should be what you want.

    Total of 7 Numbers drawn. Total of 45 numbers to be drawn from.

    (45*44*43)/(7*6*5) which results in a 1 in 405.429 chance. (3 With Bonus)
    (45*44*43)/(6*5*4) which results in a 1 in 709.50 chance. (3 With no bonus)
