Question
The names of 14 students from section A, 15 students
from section B and 16 students from section C were selected. The age of all the 45 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?Solution
The total number of students = 45 When 1 name was selected from 45 names, the probability that he was of section B = 15/45 = 1/3 But from the question, there are 15 students from the section B and the age of all 15 are different therefore, the probability of selecting one i.e. youngest student from 15 students will be 1/15.
