What is A ∩ B if A = {10, 20, 30, 40, 50, 60} and B = {10, 40, 60}?

To find the intersection of sets A and B, denoted as A ∩ B, we look for the elements that are present in both sets.

Set A contains the elements: 10, 20, 30, 40, 50, and 60.

Set B contains the elements: 10, 40, and 60.

Now, we identify which elements from set B are also in set A:

• 10 is in A
• 40 is in A
• 60 is in A

Thus, the elements that A and B have in common are 10, 40, and 60. Therefore, the intersection A ∩ B is:

A ∩ B = {10, 40, 60}
