Quantitative Aptitude ( CCS) Probability

Four persons are chosen at random from a group of 3 men, 5 women and 4 children. What is the probability of exactly two of them being men?

10/60

12/55

25/60

13/60

Total People = 3 + 5 + 4 = 12
n(s)=12c4
Probability of exactly two men and two from others
N(e) = 3c2*9c2
⇒ P= (3c2*9c2)/12c4=>12/55

Hence, option 2 is the correct answer.
