Answer 1

Given data:

The numbers of student like comedies are c=12.

The numbers of student like drama are d=18.

The numbers of student like documentaries are D=13.

The numbers of student like new program are n=7.

The expression for the perecentage of the students who like comedies is,

`p=(c)/(c+d+D+n)*100`

Substitute the given values in the above expression.

`\begin{gathered} p=(12)/((12+18+13+7))*100 \\ =24\text{ percentage} \end{gathered}`

Thus, the perecentage of the students who like comedies is 24%.
