Question 1051896: Hi TUTORS,
Just need help with the setup not the answer thanks


In a survey of 178 pet owners, 95 said they own a dog, and 83 said they own a cat. 37 said they own both a dog and a cat? How many owned a dog but not a cat?

95 own a dog means that 95 of them own just a dog OR a dog and a cat. So if you subtract the number of people that own a dog and a cat, you get the number of people that own just a dog.

As an aside, in order for all of the given information to be true, it must also be true that 37 of the original 178 pet owners must own at least one pet and none of the pets that these other 37 people own can be a dog or a cat.
