Given the following set:
A = {2,3,4,5}
B = {5,6,7,8}
C = {7,8,9,10}
Find the complement of set A union B.
The complement of the set A union B is defined as all the elements that are in the universal set but not in the set A union B.
First, we need to find the union of sets A and B:
A union B = {2,3,4,5,6,7,8}
The universal set for this problem is assumed to be all integers, so let's say the universal set is {1,2,3,4,5,6,7,8,9,10}.
Now, the complement of A union B would be:
Complement of A union B = {1,9,10}
Therefore, the complement of set A union B is {1,9,10}.
