The names of 10 students from section A, 12 students from section B and 14 students from section C were selected. The age of all the 36 students was different. Again, one name was selected from them and it was found that it was of section B. What was the probability that it was the youngest student of the section B?
The total number of students = 36 When 1 name was selected from 36 names, the probability that he was of section B = 12/36 = 1/3 But from the question, there are 12 students from the section B and the age of all 12 are different therefore, the probability of selecting one i.e. youngest student from 12 students will be 1/12.
