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

Mathematics JAMB 2000

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

  • {1, x}
  • {x y}
  • {x} checkmark
  • ΙΈ

The correct answer is: 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}

NB: The set Pβˆ’Q consists of elements that are in P but not in Q.

There is an explanation video available .
