Explanation:

Step1: Count the frequency of each breed

Let's count how many times each breed appears in the list. For example, for Whippet, we count the number of occurrences.

Step2: Calculate relative - frequency

The relative - frequency of a breed is calculated as the frequency of that breed divided by the total number of data points. First, find the total number of data points (sum of all frequencies). Then, for each breed, divide its frequency by the total number of data points.

Breed	Frequency	Relative Frequency
Mixed breed	11	$\frac{11}{45}\approx0.244$
Other purebred	2	$\frac{2}{45}\approx0.044$
Labrador retriever	3	$\frac{3}{45}\approx0.067$
Border collie	15	$\frac{15}{45}\approx0.333$
Australian shepherd	11	$\frac{11}{45}\approx0.244$
