Assume that you're designing card game for a casino. Let the random variable X denote the net winning, in dollars, for a player on each hand. (For example, X = 5 means that the player wins $5 on a hand, and X = ?1 means that he/she loses $1. This has nothing to do how much money you have to put down in order to play.) You would like to ensure that the casino makes money in the long run while at the same time the game is interesting enough to attract players. What kind of values for E[X] and Var(X) are reasonable to use and why?
