1.	If A and B are two events such that A ≠ Φ, B = Φ, then(a) PAB=PA∩BPB (b) PAB=PA PB(c) PAB=PBA=1 (d) PAB=PAPB
Answer» If A and B are two events such that A ≠ Φ, B = Φ, then (a) $P (\frac{A}{B}) = \frac{P (A \cap B)}{P (B)}$ (b) $P (\frac{A}{B}) = P (A) P (B)$ (c) $P (\frac{A}{B}) = P (\frac{B}{A}) = 1$ (d) $P (\frac{A}{B}) = \frac{P (A)}{P (B)}$
