Let U={q,r,s,t,u,v,w,x,y,z}, A={q,s,u,w,y}, and C={v,w,x,y,z}. List the elements in the set C ′∩A′.

Answer 1

A
{w, y}

B
{q, r, s, t, u, v, x, z}

C
{r, t}

D
{q, s, u, v, w, x, y, z}

Answer 2

First find the complement of C:
C' = {q, r, s, t, u}
and the complement of A:
A' = {r, t, v, x, y}
The complements are the elements that are not members of the set C and not members of the set C.
