Question

In a survey of 156 pet owners, 27 said they own a dog, and 91 said they own a cat. 3 said they own both a dog and a cat. How many owned neither a cat nor a dog?

Answer 1

Answer:

44 people owned neither a cat nor a dog

Step-by-step explanation:

We can refer to the Venn diagram attached for more details on how to solve this.

The pet owners with only dogs will be obtained by 27 -3 = 24

The pet owners with only cats = 91-3 = 88

The people with neither cats nor dogs can be obtained by subtracting the sum of the people with only cats and only dogs from the total number of people in the survey.

this is 156 - (24 + 88) = 44

44 people owned neither a cat nor a dog
