Answer
Explanation:
Step1: Recall join - relative frequency formula
Join relative frequency = $\frac{\text{Frequency of the category}}{\text{Total frequency}}$
Step2: Identify relevant frequencies
The frequency of adults who like popcorn is 20, and the total frequency of all data is 50.
Step3: Calculate join - relative frequency
$\frac{20}{50}=\frac{2}{5}$
Answer:
$\frac{2}{5}$
