SOLUTION: Let U={1,2,3,4,5,6,7,8,9,10} Let A={1,2,4,6,9,3} Let B={1,3,4,5,8} Let C={4,5,9,3} How to determine C-A'

Question 983594: Let U={1,2,3,4,5,6,7,8,9,10}
Let A={1,2,4,6,9,3}
Let B={1,3,4,5,8}
Let C={4,5,9,3}
How to determine C-A'
Answer by MathLover1(20855) (Show Source): You can put this solution on YOUR website!

A' --> complement of subset A --> all elements in but not in
if
U={1,2,3,4,5,6,7,8,9,10} and
A={1,2,4,6,9,3}
then
A' = {5,7,8,10}
if C={4,5,9,3} and A' = {5,7,8,10}, then C-A' is:
by def: The difference or relative compliment of two sets C and A', denoted by
C-A' is the set of all elements in C that are not in A'.
as you can see, none of elements in C are in A',so
C-A'={4,5,9,3}=C
