1) If A,B , C arte three events associated witha random experiment, then $P(A)P(\frac{B}{A})P(\frac{C}{A}\cap B)$ is A) $P(A \cup B\cap C)$ B) $P(A \cap B\cap C)$ C) $P(\frac{C}{A} \cap B)$ D) $P(\frac{B}{A} )$ Answer: Option BExplanation:$P(A)P(\frac{B}{A})P(\frac{C}{A}\cap B)$ = $P(A\cap B)P (\frac{C}{A}\cap B)$ =$\frac{P(A \cap B)P[C\cap (A\cap B)]}{P(A\cap B)}$ =${P(A \cap B\cap C)}$
