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:

$\frac{2}{5}$
