Yоu plаy а gаme where the amоunt yоu win (or lose, if negative) can be $1,000, $100, $0, or -$2,000. Let X be the amount you win (or lose), and assume the distribution of X is the following: P(X = 1,000) = 0.1, P(X = 100) = 0.5, P(X = 0) = 0.2, and P(X = -2,000) = 0.2. X P(X) 1000 0.1 100 0.5 0 0.2 -2000 0.2 Match the answers for the following questions:
