In a survey of 118 pet owners, 78 said they own a dog, and 44 said they own a cat. 26 said they own both a dog and a cat. How many owned neither a cat nor a dog?

Answer 1

Total number of people surveyed = 118

Number of people who own dogs = 78

Number of people who own cat = 44

Number of people who own both cats and dogs = 26

Number of people who only own dogs = 78 - 26 = 52

Number of people who own only cats = 44 - 26 = 18

Only dog owners + Only cat owners + Both + Neither = Total people surveyed

52 + 18 + 26 + Neither = 118

Neither = 22(answer)
