Final answer:
The intersection of sets H and K is defined as the set of elements that are common to both sets.
Step-by-step explanation:
The intersection of sets H and K, denoted as H ∩ K, is defined as the set of elements that are common to both H and K. In other words, it contains all the elements that are present in both sets.
For example, if H = {2, 4, 6, 8} and K = {6, 8, 10, 12}, then H ∩ K = {6, 8} because these are the elements that are present in both sets.
