im in need of some help explaining some lotto odds
here in Australia we have a 45 number game, 6 numbers are drawn if you hit all 6 you win,
now on there website it has the odds of winning, on 1 game where you pick 6 numbers your odds are 8,145,060:1
8,145,060 being the number of combination's you can make up with all 45 numbers
on twelve games where you pick 6 numbers in each game your odds are 678,755:1
this does not make sense to me??
i know that 8,145,060 divided by 12 = 678,755
but for twelve games wouldn't you just minus 12 from 8,145,060 to make the odds 8,145,048:1 on twelve games???
any help much appreciated
