    A bag contains 16 black and 18 white balls. One ball is drawn at random. What is the probability that the ball drawn is white?

    A 4/17 Correct Answer Incorrect Answer
    B 8/17 Correct Answer Incorrect Answer
    C 3/17 Correct Answer Incorrect Answer
    D 9/17 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution
