What is the best strategy to determine the total number of students in a class with multiple pet ownerships?

Using a Venn diagram is a highly effective strategy for determining the total number of students in a class with multiple pet ownerships. This method allows for a visual representation of the different groups in the problem — in this case, the students who own various types of pets.

With a Venn diagram, you can illustrate the overlaps between different categories, such as students who own dogs, cats, or both. The intersections of the circles represent students who fall into multiple categories, helping to avoid double counting. By calculating the individual sections of the Venn diagram, one can accurately determine the total number of unique pet owners in the class.

This visualization simplifies the process of understanding relationships between the groups involved, making it easier to calculate the total number of students accurately. Thus, drawing a Venn diagram not only provides clarity but also ensures that all aspects of the pet ownership are counted appropriately.
