Most, if not all, scratch-type games use "odds" to stand for probabilities.
This calculator uses those "odds" as the probabilities input into the expected value formula.


What does all this mean? If you pay $1 for a ticket, and your expected winnings are $0.72, then you would expect a net loss of $0.28 per ticket. Hence, if you bought 100 tickets, you would experience a net loss of $28! The more you buy, the more you lose!
