The intersection of sets A and B is the set of elements that are common to both sets. Looking at the given sets:
Set A = {2, 3, 8, 10, 12}
Set B = {4, 7, 8, 9, 11}
The intersection of sets A and B, denoted as A ∩ B, is the set of elements that appear in both sets. In this case, the intersection is:
A ∩ B = {8}
So, the intersection of sets A and B is the set {8}.
