Give a quick stream of consciousness before answering the following question. Three 6 faced dice are thrown together. The probability that exactly two dice show the same number on them is ?
Options:
(A) 5/16
(B) 5/12
(C) 5/19
(D) 5/17
(E) 5/15
Using question number 11 and 12, we get the probability as
1 - (1/36 + 5/9) = 5/12
The answer: (B).
