Help on odds question

  1. Nov 13, 2011 #1
    Hi all!

    Here in Australia we have a lottery called Tattslotto which uses a fairly conventional system of 6 lotto balls being drawn from 45. There are also 2 supplementary numbers drawn. We have the usual multiple picks of 6 lotto numbers and there's also system entries, ranging from system 7 to sytem 20. With system 20 for example, you can pick 20 numbers and it covers 38,760 combinations. The minimum combination for winning is 3 numbers plus one supplemntary number which would amount to twice as much winnings as what it cost to play. My question is this.....what is the statistical probability of winning using this system?

    Hope someone here could answer this for me

    Kindest Regards
