A single die is rolled twice. the set of 36 equally likely outcomes is {(1, 1), (1, 2), (1,3), (1,4), (1,5), (1,6), (2,1), (2, 2), (2, 3), (2, 4), (2,5), (2,6), (3, 1), (3, 2), (3, 3), (3, 4), (3,5), (3,6), (4,1),(4,2), (4,3), (4,4),(4,5),(4.6), (5,1), (5,2), (5,3), (5, 4), (5,5), (5,6), (6, 1), (6,2), (6,3), (6,4), (6,5), (6, 6)). a. find the probability of getting two numbers whose sum is greater than 9.(3 points) b. find the probability of getting two numbers whose sum is less than 13. (3 points) c. find the probability of getting two numbers whose sum is greater than 9 and less than 13. (3 points)
