An ordinary (fair) die is a cube with the numbers I 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 4 or 5 (or both). Round your answers to two decimal places.
