Answer:
1/6
Step-by-step explanation:
On a fair die, there is a 1/6 chance of rolling any specific number for each die,
to roll a 10 you need (5, 5) or (6, 4) or (4, 6)
odds to roll a 10 are 1/6•1/6 + 1/6•1/6 + 1/6•1/6 = 3/36
to roll an 11 you need a (5, 6) or (6, 5)
odds to roll an 11 are 1/6•1/6 + 1/6•1/6 = 2/36
to roll a 12 you need a (6, 6)
odds to roll a 12 are 1/6•1/6 = 1/36
so odds to roll a sum greater than 9 are 3/36 + 2/36 + 1/36 = 6/36 = 1/6
