How to win the lottery: the amount of possible number combinations in a drawing is very large, yet still finite. If the cash prize becomes very high- one could hypothetically purchase all or most of the combinations,for one dollar per pick, win, and still come out ahead. A group from Australia did just that a few years ago- the prize was over 200 million bucks; the Australians bought about 80% of all the tickets, spending millions; they won....they still took a chance-they could not buy all the possible combinations because others beat them to these other purchases...
