Question 468967: Given U = {10,11,12,13,14,15,16,17,18,19,20}, A= {11,13,15,19}, & B= {10,12,14,15,16,19}.
Find A' union B' Show all work on finding A', then B' then the union
Answer by Edwin McCravy(20060)   (Show Source):
You can put this solution on YOUR website! given U={10,11,12,13,14,15,16,17,18,19,20}, A={11,13,15,19} & B={10,12,14,15,16,19}
find A' ᑌ B' Show all work on finding A', then B' then the union
A' is the set of all elements of U that are not elements of A,
so A' = {10,12,14,16,17,18,20}.
B' is the set of all elements of U that are not elements of B,
so B' = {11,13,17,18,20}.
Therefore
A' ᑌ B' = {10,12,14,16,17,18,20} ᑌ {11,13,17,18,20}
ᑌ means to get the set of all those elements that are in
the sets on both sides of the symbol ᑌ, whether they are
in common or not.
A' ᑌ B' = {10,11,12,13,14,16,17,18,20}
