You pay 2 to play a game of overUnder in which you will roll

You pay $2 to play a game of \"over/Under\", in which you will roll two dice and note the sum of the results. You can bet that the sum will be less than 7 (under), exactly 7, or greater than 7 (over). If you bet\" under\" and you win, you get your $2 back, plus $2. If you bet 7 and you win, you get your $2 back plus $4, and if you bet \"over\" and win, you get your $2 plus $2 more. What are the expected wining of each type of bet?
