    Question

    In a box there are 3 red, 6 blue, and 9 yellow cards.

    One card is picked up randomly. What is the probability that it is neither red nor yellow?
    A 3/4 Correct Answer Incorrect Answer
    B 1/3 Correct Answer Incorrect Answer
    C 5/3 Correct Answer Incorrect Answer
    D 4/3 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Total number of cards = 9 + 3 + 6 = 18 Let E= event that the card drawn is neither red nor yellow = event that the card drawn is blue.  ∴ n(E) = 6 ∴ P(E) = 6/18 = 1/3
