An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.

Compute the probability of each of the following events:

Event : A The sum is greater than 9 .
Event : B The sum is divisible by 6 .
Write your answers as exact fractions.

P (A) =

P (B) =
