What is the probability that the relative position in which the consonants appear remain unchanged when the letters of the word Math are re-arranged?
A. 1/4
B. 1/6
C. 1/3
D. 1/24
E. 1/12
IMO -[spoiler] B
3 consonants - M T H
*M*T*H*
There are 4 places out of which we have to chose 1 for A which can be done in 4 ways
and thus 4/24
Has it been 2 vowels then after selecting 2 positions, we have to permute them in 2! ways, Experts, please confirm
