Let A = {3, 7, 10, 14, 17} and B = {1, 4, 6, 7, 10, 14}. What is A ∩ B?
Note
A ∩ B means the elements common to both sets. Check each element and keep only those appearing in both A and B. The intersection keeps only the elements shared by both sets. Elements that appear in just one set are left out. The correct answer is {7, 10, 14}, which matches the calculation or reasoning shown.
