The probability of occurrence of an event $B$ is $P$, The probability that events $A$ and $B$ occur together is $Q$. The probability that $A$ occurs without $B$ occuring is $R$. Then the probability of $A$ occuring is

1. $P +Q + R$
2. $P+Q-R$
3. $Q +R$
4. $P -Q -R$

Just Draw Venn Diagram and see what is A.

$R+Q$, as evident by the Venn diagram.
