If the universal set U is defined by U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} and
A = {1, 2, 3, 4 }
B = {3, 4, 5, 6, 7}
g) What is contained in the complement of the union of A and B ?
A U B = {1,2,3,4,5,6,7]
(A U B)' = {8,9,10}
===================================
h) What is the cardinality of A U B ?
Cardinality = # of elements = 7
