    If\[P(A)=0.65,\,\,P(B)=0.15\], then\[P(\bar{A})+P(\bar{B})\]is equal to:

    A) \[1.5\]

    B) \[1.2\]

    C) \[0.8\]

    D)   none of these

    Correct Answer: B

    Solution :

    Given that,\[P(A)=0.65,\,\,P(B)=0.15\] \[\therefore \]  \[P(\bar{A})+P(\bar{B})=1-P(A)+1-P(B)\]                 \[=2-0.65-0.15\]                 \[=1.20\]
