Answer
Explanation:
Step1: Recall joint - relative frequency formula
Joint relative frequency = $\frac{\text{Frequency of the joint category}}{\text{Total number of data points}}$
Step2: Identify values from the table
The number of students who like running and swimming is 28, and the total number of students is 200.
Step3: Calculate the joint relative frequency
$\frac{28}{200}=0.14$
Step4: Convert to percentage
$0.14\times100 = 14%$
Answer:
14%
