Question

The sets A and B are defined as follows: A = {1, 2, 3, 4, 5} and B = {3, 4, 5, 6, 7}. What is A ∩ B (the intersection of sets A and B)?

Answer 1

The intersection of sets A and B is {3, 4, 5}.

Step-by-step explanation:

The intersection of sets A and B, denoted A ∩ B, is the set that contains the elements that are common to both sets A and B. In this case, A = {1, 2, 3, 4, 5} and B = {3, 4, 5, 6, 7}. To find the intersection, you need to identify the elements that appear in both sets.

Looking at the sets, we can see that the elements 3, 4, and 5 are common to both sets A and B. Therefore, the intersection of sets A and B is A ∩ B = {3, 4, 5}.
