An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented bypainted spots). imagine that such a die is rolled twice in succession and that the face values ofthe two rolls are added together. this sum is recorded as the outcome of a single trial of arandom experiment. compute the probability of each of the following events: event a: the sum is greater than 5.event b: the sum is not divisible by 4.
