    Question

    A bag has 6 red balls, 6 blue balls and 8 green balls. Two

    balls are picked randomly. What is the probability that at least one of them is green?
    A 63/95 Correct Answer Incorrect Answer
    B 31/95 Correct Answer Incorrect Answer
    C 62/95 Correct Answer Incorrect Answer
    D 61/95 Correct Answer Incorrect Answer
    E 60/95 Correct Answer Incorrect Answer

    Solution

    Total balls = 6 + 6 + 8 = 20
    Non-green balls = 6 + 6 = 12
    Required probability = 1 - (12/20) × (11/19)
    = 1 - (132/380)
    = 1 - (33/95)
    = 62/95
