Disco's lottery win prompted me to wonder why the tickets in those lotteries are drawn the way they are. They should be drawn from the top down - that is, big home, smaller home, leaky condo, trips/cars etc, down to $100 gift certificates and each winning ticket set aside. But the tickets are put back into the pot after each group draw. It is theoretically possible for the winner of the grand prize home to also win two more homes, a trip, a car, etc etc. By re-entering each ticket into each draw it lessens the chances (marginally) of everyone still in the pot. Is there some logical reason it's done this way? or is it a legal thing? Doesn't make sense to me if you've already won a big prize to still be eligible for the smaller ones.
