I pasted the correctly calculated odds above. Jackpots are paid for the extremes, so there are 2 jackpots. The odds don't change.
When you play AON 1 to 12 is the same then 13 to 24.
When you play a regular lotto, it is different, there is only one jackpot, that eventually is split because there are several winners.
If you play pick 3, ten different lines, your odds are 10:1000, the notation 1:100 might be seen on a playslip. The scientific notation would be 0.01.
Only one combination can win the first price straight, the others loose, unless there is a promotion like, payback if the last digit matches.
We say that a won bet pays 2:1 (douzaine roulette), but we say that your odds are 1:2 (50%).
You mix it up.
Are the odds 100 to 1 or are they really 990 to 1?
If you play 10 combinations at pick 3, then you did not cover 990 combinations.
The chance for the winning combination is the same, 1/1000.
10 * 0.001 + 990 * 0.001 = 1.
0.01 + 0.99 = 1.
Sure looks like two different ways to calculate the odds to me.
The chance that the winning combination is in the not played set, is much bigger (1-0.01=0.99).
The chance is 1/1000, no matter how you turn it. The chance of winning net cash is a different calculation involving the odds (chances, probability).
In any case the chance to guess the winning combination is 1/1000.
If you cover 1000 combinations, your chance is 1/1000*1000=1!
You will pay 1000 dollars and you will probably get 500 dollars.
You lost 500 and the lottery earned 500.
Your payout ratio is by consequence +500/-1000 = -0.5.
