    If A and B are two mutually exclusive events, then                                                                                             \[P\,(A+B)=\]                          [MNR 1978; MP PET 1991, 92]

    A)                                                                                     \[P\,(A)+P\,(B)-P\,(AB)\]                                                                                  

    B)                                                                                            \[P\,(A)-P\,(B)\]

    C)                                                                                           \[P\,(A)+P\,(B)\]                                                                                         

    D)                                                                                    \[P\,(A)+P\,(B)+P\,(AB)\]

    Correct Answer: C

    Solution :

                                                                                                                \[P(A)+P(B)\]  (Fundamental concept).
