Studdy Solution

STEP 1

Assumptions1. The number of customers who own dogs is27. The number of customers who own mice is303. The number of customers who own both dogs and mice is17

STEP 2

To find the number of customers who own either a dog or a mouse, we need to add the number of dog owners and the number of mouse owners. However, since the customers who own both have been counted twice (once in the dog owners and once in the mouse owners), we need to subtract the number of customers who own both.
Numberofeitherdogormouseowners=Numberofdogowners+NumberofmouseownersNumberofbothdogandmouseownersNumber\, of\, either\, dog\, or\, mouse\, owners = Number\, of\, dog\, owners + Number\, of\, mouse\, owners - Number\, of\, both\, dog\, and\, mouse\, owners

STEP 3

Now, plug in the given values for the number of dog owners, mouse owners, and both dog and mouse owners to calculate the number of either dog or mouse owners.
Numberofeitherdogormouseowners=27+3017Number\, of\, either\, dog\, or\, mouse\, owners =27 +30 -17

STEP 4

Calculate the number of either dog or mouse owners.
Numberofeitherdogormouseowners=27+3017=40Number\, of\, either\, dog\, or\, mouse\, owners =27 +30 -17 =40So,40 customers own either a dog or a mouse.
