A group of students were surveyed about which type of party they would most want to attend.
\begin{tabular}{|c|c|c|c|}
\hline & Boy & GIrl & Total \\
\hline Bowling & 9 & $f$ & 15 \\
\hline Paintball & 15 & 10 & 25 \\
\hline Skating & 6 & 14 & 20 \\
\hline Total & 30 & 30 & 60 \\
\hline
\end{tabular}
What is the experimental probability that the next student randomly selected will be a boy who would most want to attend a skating party?
1/10
3/10
