If A and B are two events such that \(P ( A ) \neq 0\) and \(P ( B \mid A )=1\) then, _________ .
- A \(B \subset A\)
- B \(A =\varnothing\)
- C \(B =\varnothing\)
- D \(A \subset B\)
Answer & Solution
Correct Answer
(D) \(A \subset B\)
Step-by-step Solution
Detailed explanation
\(P ( B \mid A ) = \frac{P ( A \cap B )}{P ( A )}\) \(1 = \frac{P ( A \cap B )}{P ( A )}\)
