If a gambler rolls two dice and gets the sum of 7, he wins $20. If he gets a sum of 4, he wins $40. The cost of playing is $14. What is the expectation of this game?
Accepted Solution

The expectation is that he should be losing money because the chances he rolls either a 7 or a 4 out of 2 dice (which is 1-12) is 1/6. I think this is what you're trying to ask I hope I helped
