The names of 16 students from section A, 18 students
from section B and 20 students from section C were selected. The age of all the 54 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 = 54 When 1 name was selected from 54 names, the probability that he was of section B = 18/54 = 1/3 But from the question, there are 18 students from the section B and the age of all 18 are different therefore, the probability of selecting one i.e. youngest student from 18 students will be 1/18.
