Question 202889
3 pts) Given U = {21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31}, A = {21, 23, 25, 27, 29}, and
B = {22, 25, 28, 29}.  Find A'U B'.

This questions asks for us to find the union (or) for sets A and B NOT, or our composite sets. 


A'={22,24,26,28,30, 31}. 
B'={21,23,24,26,27,30,31}. 


Our Union of the sets is A' U B'= {21,22,23,24,26,27,28,30,31}.


**Notice how we lost both numbers 25 and 29 from set U!
