Step 1: Calculate the complementary event

            GIVEN:  P(E) = 0.05

              The complementary event 'not E' = \bar{E} = ?

       

          We Know that

                  Sum of the complementary events = 1

                          P(E) + P(\bar{E}) = 1

                             0.05 + P(\bar{E}) = 1

                                          P(\bar{E}) = 1 - 0.05

                                          P(\bar{E}) = 0.95


          Thus, the probability of 'not E' = 0.95
