He writes the name of each student on a separate card, the cards being identical. Then he puts cards in a bag and stir them thoroughly. He then draws one card from the bag. What is the probability that the name written on the card is the name of a girl?

  1. $\dfrac{1}{11}$
  2. $\dfrac{5}{11}$
  3. $\dfrac{7}{11}$

  4. None of these

D Correct answer
Explanation

Total students = 44. Girls = 12. Probability = 12/44 = 3/11. Since 3/11 is not listed in the options, 'None of these' is correct.

AI explanation

The total number of students in class X is 44, and the number of girls is 12. Using the classical definition of probability, the probability of selecting a girl's card is the number of girls divided by the total number of students. This calculation gives 12/44, which simplifies to 3/11. Since 3/11 is not listed among the provided options, the correct choice is None of these.
