To determine probability of given event.

Answer to Problem 2ACYP
Probability of getting double or sum of 9 is
Explanation of Solution
Given information :
Two dice are rolled.
Total possible outcome while rolling 2 dice are
Possibilities of doubles on the two dice are,
(1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6)
Hence the probability is
Possibilities of getting a sum of 9 are,
(3,6), (4,5), (5,4), (6,3)
Hence the probability of getting sum of 9 is
Hence probability of getting double or sum of 9 is
