    If 4 coins are tossed, find the probabilities

    If 4 coins are tossed, find the following probability:

    2 heads.

    more than 3 tails.

    2 heads would be 1/16.
    I don't know how to do more than 3 tails.

    No that is not correct. P(\text{two heads})=\frac{_4C_2}{2^4}=\frac{6}{16}
