Answer:
5/9.
Explanation:
The total number of outcomes on rolling 2 dice is 6*6 = 36.
List of an even sum = 1-1, 1-3, 1-5, 2-2, 2-4,2-6, 3-1, 3-3 , 3-5, 4-2, 4-4, 4-6, 5-1,5-3, 5-5, 6-2, 6-4 and 6-6. Total = 18.
The list of the sums greater than 9 ( but not in the first list) = 5-6, 6-5. Total 2.
So the required probability = 20/36
= 5/9.
