Answer

Explanation:

Step1: Find total number of students surveyed

Add up the frequencies of all genres. $10 + 8+9 + 11+12=50$.

Step2: Find number of students who prefer comedies

The frequency of students who prefer comedies is 10.

Step3: Calculate the proportion

The proportion is the number of students who prefer comedies divided by the total number of students surveyed. So the proportion $p=\frac{10}{50}=\frac{1}{5}=0.2$.

Answer:

$0.2$
