For a Pick 6 from 45 with 2 Bonus Numbers from the same 45 the usual Formulae given is: -

    6                                                          45c6
    5 plus Bonus                                        45c6 / 6c5 x(39c1-37c1)
    5                                                          45c6 / 6c5 x 37c1
    4                                                          45c6 / 6c4 x 39c2
    3 plus one or both Bonus Numbers     45c6 / 6c3 x (39c3 - 37c3)

Without revealing your formulae is there any dissention over these formulae?
If not what would be your breakdown on the 3 plus Bonus, 4 and 5 Wins over say 1234 Draws playing 28 Games per Draw?

Happy calculating.

Colin

    Colin -

    I haven't done too much with games that have two bonus balls, but I have formulae posted on my site:

      John

      Thanks for your response. I congratulate you on maintaining such an excellent site and recommend it to anyone wanting Probability information on Lotto Games.

      The problem I had was old code versus new code and is now sorted. I can now run both the Powerball and Standard Lotto type games with Random Number Selections against Random Number Draws and get results compatible with those expected from applying Probability Formulae.

      Anybody got a suspicious Lotto History they would like me to test?

      Regards

      Colin
