Answer:

Try to understand it. ..

Explanation:

Theorem 1. The probability of the complementary event A' of A is given by P(A') = 1 – P(A). Proof: The events A and A' are mutually disjoint and together they form the whole sample space. A ∪ A' = S ⇒ P(A ∪ A') = P(S) or, P(A) + P(A') = P(S) = 1 ⇒ P(A') = 1 − P(A).
