    DIRECTIONS: The questions in this segment consists of two statements, one labelled as "Assertion A" and the other labelled as "Reason R". You are to examine these two statements carefully and decide if the Assertion A and Reason R are individually true and if so, whether the reason is a correct explanation of the assertion. Select your answers to these items using codes given below. Assertion: Probability of drawing a red face card from a pack of 52 playing cards is\[\frac{3}{26}\] Reason: Probability of not selecting a queen from a pack of 52 cards is \[\frac{1}{13}\]

    A)  If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

    B)  If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.

    C)  If Assertion is correct but Reason is incorrect.

    D)  If Assertion is incorrect but Reason is correct.

    Correct Answer: B

    Solution :

         Assertion is true Total no. of possible outcomes = 52 Number of red face cards = 6 P (red face card) \[=\frac{6}{52}=\frac{3}{26}\] Reason is false P (not selecting a queen)\[=1-\frac{1}{13}=\frac{12}{13}\]
