A game is played with the following rules. Two ordinary number cubes, each with six sides labeled 1 to 6, are rolled. After each roll, a player is given a certain number of points depending on the outcome. If the sum is 2 or 12, the player receives +5 points. If the sum is 3 or 11, the player receives +2 points. If the sum is any other number, the player receives -1 points. What is the expected value of the number of points a player will receive after a roll?
