Math Question

In conditional probability, the notation \( \mathrm{P}(\mathrm{A} \mid \mathrm{B}) \) is read:
"The probability of event A occurring given that event B has occurred."
For example: In the following two-way table \( P( \) Walk to school \( \mid \) Sophomore \( )=3 /(2+25+3)=0.1 \)
\begin{tabular}{|c|c|c|c|}
\hline Grade & Drive to school & Take the bus & Walk \\
\hline Sophomore & 2 & 25 & 3 \\
\hline Junior & 13 & 20 & 2 \\
\hline Senior & 25 & 5 & 5 \\
\hline
\end{tabular}
P(Take the bus / Sophomore ) = [?] Round to the nearest hundredth.
