A street vendor is asking people to play a simple game. You roll a pair of dice. If the sum on the dice is 10 or higher, you win $10. If you roll a pair of 1's, you win $59. Otherwise you lose $5. If the random variable X equals your win (or loss) for each play. Find standard deviation and variance (i.e. figure out how much we expect to win or lose for each play on average). Is it wise to play this game? Why?
