Question
The names of 7 students from section A, 5 students from
section B and 3 students from section C were selected. The age of all the 15 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 = 15 When 1 name was selected from 15 names, the probability that he was of section B = 5/15 = 1/3 But from the question, there are 5 students from the section B and the age of all 5 are different therefore, the probability of selecting one i.e. youngest student from 5 students will be 1/5.
