Question

a restaurant offers cheese, pickles, and ketchup for burger toppings. use the venn diagram below to determine how many people ordered a burger with just ketchup. just ketchup = type your answer... people

Explanation:

Step1: Understand the Venn diagram

The Venn diagram has three circles for cheese, pickles, and ketchup. We need to find the number of people who ordered just ketchup.

Step2: Locate the relevant region

In a Venn diagram, the region that represents only one set (in this case, only ketchup) is the part of the ketchup circle that does not overlap with the cheese or pickles circle. Looking at the standard Venn - diagram numbering for three - set cases (where each number represents the number of elements in that particular region), the region for just ketchup is numbered 7.

Answer:

7
