The two way table shows the following totals;
[tex]\begin{gathered} Sports=65 \\ \text{Music / Drama=25} \\ \text{Work}=10 \end{gathered}[/tex]
The probability that a randomly selected student is in music/drama therefore is;
[tex]\begin{gathered} P\lbrack E\rbrack=\frac{Number\text{ of required outcomes}}{Number\text{ of all possible outcomes}} \\ P\lbrack\text{ music/drama\rbrack=}\frac{25}{100} \\ P\lbrack\text{ music/drama\rbrack=0.25} \end{gathered}[/tex]
