Explanation:

Step1: Recall Venn diagram properties

In a Venn diagram with three sets (big - box, online, locally - owned), the number of elements in the intersection of all three sets is the value that is common to all three circles.

Step2: Identify the intersection value

Looking at the Venn diagram, the number in the intersection of the big - box, online, and locally - owned store circles is \(18\).

Answer:

\(18\)
