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
