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