Use the Venn diagrams to respond to the problems. (Hint: You may use the same data provided in the two-way table from problem 3 to help make sense of the Venn diagram.)

For problems 1–5, use the Venn diagram, which represents the relationship between favorite sport (soccer or baseball) and pet ownership (own a pet or doesn’t own a pet).
