A red die and a blue die are rolled. You win or lose money depending on the sum of the values of the two dice. If the sum is 3, 10, or 12, you win $5. If the sum is 5 or 11, you win $1. If the sum is any other value (2, 4, 6, 7, 8, or 9), you lose $2. Let X be a random variable that corresponds to your net winnings in dollars. What is the expected value of X? E[X]=Ex: 1.23
