5 พิจารณาจากเซต 2 เซต คือ A = {d, e, f } และ B = {e, f, g, h, k} สร้างเซตใหม่จากเซต A และเซต B คือ C = { e, f } เรียกเซต C ว่า อินเตอร์เซกชันของเซต A และเซต B ดังนั้น C = = { e, f }
2 set the set is 5 A = {d, e, f} and B = {e, f, g, h, k}. Create a new set from the set A and set B is C = {e, f}. Call the set C that the intersection of A and B set. Therefore, C = = {e, f}.
5 Consider the set of two sets is A = {d, e, f} and B = {e, f, g, h, k} generate new set from A and Set B is C = {e, f} a subset C. the intersection of set A and set B , so C = = {e, f}.
5 considering the set 2 set is A = {,,} and D E F B = {E F G H,,,,} create new K set from a set and the set A B is C = {,} e f call set. C that intersection of sets A and set B so C = = {,} e f .
