In which three balls are selected simultaneously and randomly from a box. But assume that the box contains 8 red balls and 4 green balls. Also assume that each red ball selected pays $0.60, that each green ball selected pays $0.30, and that it costs $1.10 to play the game. A random variable XX is defined to be the net payoff for a player. How many different values are possible for the random variable XX?
