    Question

    What will be the value of P(not E) if P(E) = 0.07?

    A 0.90 Correct Answer Incorrect Answer
    B 0.007 Correct Answer Incorrect Answer
    C 0.93 Correct Answer Incorrect Answer
    D 0.72 Correct Answer Incorrect Answer
    E 0.03 Correct Answer Incorrect Answer

    Solution

    If the probability of happening of an event P(E) and that of not happening is P(E), then P(E) + P(not E) = 1 So, P(not E) = 1 - P(E) Since P(E) = 0.07 P(not E) = 1 - 0.07 P(not E) = 0.93
