An event has odds in favour $4 : 5$, then the probability that event occurs, is
$\frac{1}{5}$
$\frac{4}{5}$
$\frac{4}{9}$
$\frac{5}{9}$
(c) Required probability $ = \frac{4}{{4 + 5}} = \frac{4}{9}.$
One card is drawn from a pack of $52$ cards. The probability that it is a queen or heart is
Let ${E_1},{E_2},{E_3}$ be three arbitrary events of a sample space $S$. Consider the following statements which of the following statements are correct
Given two independent events $A$ and $B$ such that $P(A) $ $=0.3, \,P(B)=0.6$ Find $P(A$ and $B)$.
Two events $A$ and $B$ will be independent, if
Given that the events $A$ and $B$ are such that $P(A)=\frac{1}{2}, P(A \cup B)=\frac{3}{5}$ and $P(B)=p .$ Find $p$ if they are independent.
