Sets - Union, Intersection, and Negation: Find (A U B) n C'

[solomon_13000]

Let U = {1,2,3,4,5,…………,12},
A={1,3,5,7,9,11},
B={2,3,5,7,11},
C={2,3,6,12},
D={2,4,8}

1. (A u B) n C’

(A u B) = {1,2,3,5,7,9,11}

C’ = ?

How do I indentify the elements for C’

 

[skeeter]

C = C={2,3,6,12}
C' = {1,4,5,7,8,9,10,11}

C u C' = U

C n C' = { }

C' is the set of elements in U that are not in C ... also called the complement of C.
