For any two events $A$ and $B$ in a sample space
For any two events $A$ and $B$ in a sample space
- [IIT 1991]
- A
$P\,\left( {\frac{A}{B}} \right) \ge \frac{{P(A) + P(B) - 1}}{{P(B)}},\,\,P(B) \ne 0$ is always true
- B
$P\,(A \cap \bar B) = P(A) - P(A \cap B)$ does not hold
- C
$P\,(A \cup B) = 1 - P(\bar A)\,P(\bar B),$ if $A$ and $B$ are disjoint
- D
None of these

For the three events $A, B$ and $C, P$ (exactly one of the events $A$ or $B$ occurs) = $P$ (exactly one of the events $B$ or $C$ occurs)= $P$ (exactly one of the events $C$ or $A$ occurs)= $p$ and $P$ (all the three events occur simultaneously) $ = {p^2},$ where $0 < p < 1/2$. Then the probability of at least one of the three events $A, B$ and $C$ occurring is
