If the odds are 1 in 292.2 million, doesn't this mean that the expected value is actually positive? If you had 292.2 million bucks, you could guarantee a win.
You could guarantee a win with 175 million or so.

You couldn't however guarantee that you'd win more than you spent -- because others could win as well, diluting the pot.
