Buying four tickets would leave 999,996 losing tickets. Perhaps I explained it incorrectly. The point I'm trying to make is that to have a one in four chance of winning you would have to buy 250,000 tickets.
At the risk of being labelled hostile, lol, you need to add three more zeroes to your numbers.
Who would claim that buying four tickets out of a million would leave you with a one in four chance of winning?
It would leave you with a (4 / 1,000,000) change of winning, which is exactly four times more than one ticket (1 / 1,000,000).
