Question

Sets A B and C are subsets of the universal set U. these sets are defined as follows.

U = {f,g,h,p,q,r,x,y,z}
A={f,g,p,x}
B={g,h,x,y}
C={p,r,x,y,z}
find C' n (A U B)'

Answer 1

{q}

Explanation:

`A \cup B={f, g, h, p, x, y} \\ \\ (A \cup B)'={q, r, z} \\ \\ \\ C'={f, g, h, q} \\ \\ \\ \therefore C' \cap (A \cup B)'={q}`
