Fraction of families having more than 2 pets = families with pets of 3 and above ÷ total number of families in the apartment

From the dot plot above, 3 families have 3 pets, and 1 family has 4 pets.

Number of families with more than 2 pets = 3 + 1 = 4

Fraction of families with more than 3 pets = $\frac{4}{20} = \frac{1}{5}$

Answer 2

The fraction of families that have more than two pets is B. $\frac{1}{5}$

Calculations and Parameters

Fraction of families having more than 2 pets = families with pets of 3 and above/total number of families in the apartment

From the dot plot above:
