    A) \[\frac{1}{4}\]

    B) \[\frac{1}{2}\]

    C) \[\frac{3}{4}\]

    D) \[1\]

    Correct Answer: A

    Solution :

    [a] Total possible outcomes are \[\{HH,\,HT,\,TH,\,TT\}\]i.e., 4 in number.
    Favourable outcomes is \[\{TT\}\] i.e., 1 in number.
    \[\therefore \]  P(getting no head) \[=\frac{1}{4}\]
