Lottery mathematics a game is Mega Millions, albeit with different jackpot odds. Where more than 1 powerball is drawn from a separate pool of balls to the main lottery (for example, in the EuroMillions game), the odds of the different possible powerball matching scores are calculated using the method shown in the "other scores" section above (in other words, the powerballs are like a mini-lottery in their own right), and then multiplied by the odds of achieving the required main-lottery score. If the powerball is drawn from the "same" pool of numbers as the main lottery, then, for a given target score,
Lottery mathematics winning numbers from the 6 winning numbers. This means that there are 6 - n losing numbers, which are chosen from the 43 losing numbers in formula_8 ways. The total number of combinations giving that result is, as stated above, the first number multiplied by the second. The expression is therefore formula_9. This can be written in a general form for all lotteries as: formula_10 where formula_11 is the number of balls in lottery, formula_12 is the number of balls in a single ticket, and formula_13 is the number of matching balls for a winning ticket. The generalisation of this
