प्रश्न
If A and B are two events such that A ≠ Φ, B = Φ, then
विकल्प
\[P\left( \frac{A}{B} \right) = \frac{P\left( A \cap B \right)}{P\left( B \right)}\]
\[P\left( \frac{A}{B} \right) = P\left( A \right) P\left( B \right)\]
\[P\left( \frac{A}{B} \right) = P\left( \frac{B}{A} \right) = 1\]
\[P\left( \frac{A}{B} \right) = \frac{P\left( A \right)}{P\left( B \right)}\]
