    A coin is tossed four times one by one. What is the

    probability of getting a tail for the first time, head for the second time and again head for the third time, and a tail for the fourth time?
    A 1/16 Correct Answer Incorrect Answer
    B 3/16 Correct Answer Incorrect Answer
    C 1/8 Correct Answer Incorrect Answer
    D 1/4 Correct Answer Incorrect Answer

    Solution

    Number of times the coin is tossed = 4
    Probability of getting a tail for the first time = 1/2
    Probability of getting a head for the second time = 1/2
    Probability of getting a head for the third time = 1/2
    Probability of getting a tail the fourth time = 1/2
    => Required probability = (1/2) (1/2) (1/2) (1/2) = 1/16
