\(\mathrm{P}(\mathrm{A} / \mathrm{A} \cap \mathrm{B})+\mathrm{P}(\mathrm{B} / \mathrm{A} \cap \mathrm{B})=\)
- A \(1\)
- B \(P(A \cup B)\)
- C \(\mathrm{P}(\mathrm{A} \cap \mathrm{B})\)
- D \(2\)
Answer & Solution
Correct Answer
(D) \(2\)
Step-by-step Solution
Detailed explanation
\(P(A / A \cap B)+P(B /(A \cap B)\) \(=\frac{P(A \cap(A \cap B))}{P(A \cap B)}+\frac{P(B \cap(A \cap B))}{P(A \cap B)}\) \(=\frac{P(A \cap B)}{P(A \cap B)}+\frac{P(A \cap B)}{P(A \cap B)}=1+1=2\)
