    A bag contains 12 black and 14 white balls. One ball is drawn at random. What is the probability that the ball drawn is white?

    A 4/13 Correct Answer Incorrect Answer
    B 5/3 Correct Answer Incorrect Answer
    C 6/13 Correct Answer Incorrect Answer
    D 7/13 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let number of balls = (12 + 14) = 26
    Number of white balls = 14
    P (drawing a white ball) = 14/26 = 7/13
