    Question

    In a game, a coin is tossed 4 times. ‘A’ wins if the

    number of heads is equal to the number of tails. What is the probability that ‘A’ wins?
    A 1/2 Correct Answer Incorrect Answer
    B 3/8 Correct Answer Incorrect Answer
    C 1/4 Correct Answer Incorrect Answer
    D 5/8 Correct Answer Incorrect Answer

    Solution

    Total number of outcomes = 2 4 = 16
    Favourable outcomes (2 heads and 2 tails) = C(4,2) = 6
    Probability that ‘A’ wins = 6/16 = 3/8
