Let P = {1, 2, u, v, w, x}; Q = {2, 3, u, v,…

Let P = {1, 2, u, v, w, x}; Q = {2, 3, u, v, w, 5, 6, y} and R = {2, 3, 4, v, x, y}.
Determine (P-Q) ∩ R

Correct Answer: Option C

Explanation

P = {1,2,u,v,w,x}
Q = {2,3,u,v,w,5,6,y}
R = {2,3,4,v,x,y}
P – Q = {1,x}
(P – Q) ∩ R = {1,x} ∩ {2,3,4,v,x,y} = {x}
