Question
The names of 15 students from section A, 10 students
from section B and 15 students from section C were selected. The age of all the 40 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 = 40 When 1 name was selected from 40 names, the probability that he was of section B = 10/40 = 1/4 But from the question, there are 10 students from the section B and the age of all 10 are different therefore, the probability of selecting one i.e. youngest student from 10 students will be 1/10.
