The chance of an event happening is the square of the chance of a second event but the odds against the first are the cube of the odds against the second. The chances of the events are
$\frac{1}{9},\,\frac{1}{3}$
$\frac{1}{{16}},\,\frac{1}{4}$
$\frac{1}{4},\,\frac{1}{2}$
None of these
Let $A$ and $B$ be two events such that $P\,(A) = 0.3$ and $P\,(A \cup B) = 0.8$. If $A$ and $B$ are independent events, then $P(B) = $

For any two events $A$ and $B$ in a sample space
Check whether the following probabilities $P(A)$ and $P(B)$ are consistently defined $P ( A )=0.5$, $ P ( B )=0.4$, $P ( A \cap B )=0.8$
