WebIf set A and set B are two sets, then A intersection B is the set that contains only the common elements between set A and set B. It is denoted as A ∩ B. Example: Set A = {1,2,3} and B = {4,5,6}, then A intersection B is: Since A and B do not have any elements in common, so their intersection will give null set.
