Solution:

The formula to solve the question is given below as

$Pr(A|B)=(P(A\cap B))/(n(B))$
$\begin{gathered} P(A\cap B)=25 \\ n(B)=95 \end{gathered}$

By substituting the values, we will have

$\begin{gathered} Pr(A\lvert B)=\frac{P(A\operatorname{\cap}B)}{n(B)} \\ Pr(A\lvert B)=(25)/(95)*100 \\ Pr(A\lvert B)=26.3\% \end{gathered}$

Hence,

The final answer is

$\Rightarrow26\%$

The SECOND OPTION is the right answer
