[Question] Three 6 faced dice are thrown together. The probability that exactly two dice show the same number on them is
Options:
(A) 5/9
(B) 5/12
(C) 1/36
(D) 7/12
(E) 4/9
[CoT] Using question number 11 and 12, we get the probability as
1 - (1/36 + 5/9) = 5/12

[Ans] (D)
[Question] In a division sum, the remainder is 0. As student mistook the divisor by 12 instead of 21 and obtained 35 as quotient. What is the correct quotient?
Options:
