Question 1194155: Let S be the universal set, where: -
S={1,2,3,...,18,19,20}
Let sets A and B be subsets of S, where: Set A={3,4,6,12,13,14,18}
Set B={1,3,7,8,11,12,15,17,19,20}
Find the following:
-LIST the elements in the set (AUB):
(AUB)=(1,3,4,6,7,8,11,12,13,14,15,17,18
LIST the elements in the set (AnB):
(AnB) =(3,12)
