At my office, 16 people own cats, 9 people own dogs, and 3 people own both cats and dogs. How many people own a cat or a dog?

22 people

Step-by-step explanation:

Using the concept of a Venn Diagram, you place the 3 people in the intersection. Then, you subtract the three from both groups to keep the balance.

Since you said "or", you just add the entirety of the population.

22

Step-by-step explanation:

n(DUC) = n(C) + n(D) - n(C^D)

n(DUC) = 9 + 16 - 3 = 22
