You can put this solution on YOUR website! 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!
