Two dice are rolled simultaneously. Find the probability of getting a total of 9.
Solution
Correct Answer: Option B
S = { (1, 1), (1, 2), (1, 3), (1, 4),(1, 5), (1, 6), (2, 1), (2, 2),.........(6, 5), (6, 6) }
=> n(S) = 6 x 6 = 36
E = {(6, 3), (5, 4), (4, 5), (3, 6) }
=> n(E) = 4
Therefore, P(E) = 4/36 = 1/9
