There are 36 possible outcomes when rolling a pair of dice, as each dice has 6 possible outcomes. To find the probability of rolling a sum of 9 or higher, we can list all the possible outcomes that satisfy this condition:

(3,6), (4,5), (4,6), (5,4), (5,5), (5,6), (6,3), (6,4), (6,5), (6,6)

There are 10 total outcomes that satisfy this condition, so the probability is 10/36 = 5/18 = 0.2778, which is closest to answer choice D.
