The two dice sum of 4: 1,3 2,2 3,1 = 3 in 36 = 1 in 12
Prob(Sum is odd) = 1/2 Prob(Sum > 6) = 15/36 = 5/12 Prob(Sum is odd or >6) = 27/36 = 3/4
It's1/12
Two standard dice cannot have a sum greater than 12. The probability, then, of getting a sum greater than 15 is zero.

The sum of 8 and 2 is 10
1/6 + 2/3 + 1/4 = 2/12 + 8/12 + 3/12 = 13/12 = 1 1/12
