Two balls are chosen randomly from an urn containing 8 white, 4 black, and 2 orange balls. Suppose that we win $\$ 2$ for each black ball selected and we lose $\$ 1$ for each white ball selected. Let $X$ denote our winnings. What are the possible values of $X,$ and what are the probabilities associated with each value?
