Question 198077
figure out (A′ U C′) ∩ B ′. Can someone please help me!!!!!!! Thank you!!!!!! 

6. (3 pts) Given U = {l, m, n, o, p, q, r, s, t, u, v, w}, A = {l, o, p, q, s, t}, B = {n, o, r, s, v, w}, 
and C = {l, m, n, q, r, t}, find (A′ U C′) ∩ B ′. 

A', list the elements of U that are NOT in A.
A’ = {m, n, r, u, v, w} 
B', list the elements of U that are NOT in B.
B’ = {l, m, p, q, t, u} 
C’, list the elements of U that are NOT in C.
C’ = {o, p, s, u, v, w}
--------------------------------------------
(A′ U C′)  = {m,n,r,u,v,w,o,p,s)
-----------------------------------
(A′ U C′) ∩ B′ = {m,p,u)
========================================
