Question

Suppose that 18​% of people have a dogdog​, 34​% of people have a cat​, and 88​% of people own both. What is the probability that someone owns a dog
or a cat

Answer 1

I believe that this should be as simple as adding 18% and 34% together since the problem utilizes the keyword "or":  18 + 34 = 52.

So, 52% of people have either a dog or a cat.
