                The second question I asked (here and on Facebook) is about playing a game with a 99.9% return (negative expectation) and getting a loss rebate equal to 20% of each $100 bet.  And the question here is different from the original question.  Do 20% rebates ever make you whole at a negative expectation game?  You will note that on Facebook there responses were divided with about half saying you will lose. Note that one of the responders is the County Treasurer of Riverside County, Calif, who said you would lose.  The reason is 20% rebates at negative expectation games are not enough to make you whole and to win you must have more winning hands..
