    For an event E, \[P\left( E \right)+P\left( \overline{E} \right)=q\], then

    A) \[0\le q<1\]

    B) \[0<q\le 1\]

    C) \[0<q<1\]

    D) None of these

    Correct Answer: D

    Solution :

    Given, \[P\left( \overline{E} \right)+P\left( \overline{E} \right)=q\] We know that, total probability of possible outcomes is 1 \[P\left( \overline{E} \right)=1-P\left( E \right)\] The value of q = 1
