There are 36 possible outcomes when two dice are rolled.

11, 12, 13, 14, 15, 16

21, 22, 23, 24, 25, 26

31, 32, 33, 34, 35, 36

41, 42, 43, 44, 45, 46

61, 62, 63, 64, 65, 66

The rolls with odd sums are shown above in bold, underline face.

There are 18 odd sum outcomes.

p(odd sum) = 18/36 = 1/2
