Question
rrect answerThe names of 5 students from section A, 6 from section B and 7 students from section C were selected. The age of all the 18 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?Options1/181/61/151/12
Solution
The probability of selecting a student from section B is 6 out of 18, which simplifies to 1/3. However, since we are looking for the probability that the selected student is the youngest from section B, we need to consider that there is only 1 youngest student in section B. Therefore, the probability is 1 out of the 6 students from section B, which simplifies to 1/6. However, since we are selecting from all 18 students, we need to multiply this probability by the probability of selecting a student from section B, which is 1/3. Therefore, the final probability is (1/6) * (1/3) = 1/18. So, the correct answer is 1/18.
