1) How many numbers do you have to predict in order to win the 1st prize?
2) Out of how many numbers in total?
3) How much is the 1st prize?
There is a possibility of buying your way up to the 1st prize, if for example there is a jackpot of 5,000,000 and the total number of possible combinations are below the 5,000,000 then you can keep the difference by playing it safe.
Example: 1st prize is for 6 numbers out of 44, but there cannot be a combination with 2 or more times the same number.
Let's say each combination costs 50 cents, how much should be the jackpot in order to cover all of the possible combinations and still make a profit after tax??
