A and B are two events such that P(A)=0.54,P(B)=0.69 and $P(A\cap B)=0.35$.Find $P(B\cap A')$

$\begin{array}{1 1}(A)\;0.34\\(B)\;0.24\\(C)\;0.14\\(D)\;0.64\end{array} $

Toolbox:
  • $P(B \cap A')=P(B)-P(B \cap A)$
$P(B \cap A)=0.35$
$P(B)=0.69$
$P(B \cap A')=P(B)-P(B \cap A)$
$\Rightarrow 0.69-0.35$
$\Rightarrow 0.34$
Hence (A) is the correct answer.
