A pet store surveyed 200 pet owners and obtained the following results: 96 people owned cats, 97 people owned dogs, and 29 people owned cats and dogs. How many people in the survey owned cats or dogs? 18. Determine whether each of the following statements makes sense: Set A and set B share only one element, so I don't need to use overlapping circles to visualize their relationship. If I am given sets A and B, the set (AUB)' indicates I should take the union of the complement of A and the complement of B. 20. Suppose that A + B. Draw a Venn diagram that correctly illustrates the relationship between the sets: AMB=B AUB A AUB B
