# 4.5.2 Operations on Sets, SPM Paper 2 (Long Questions)

Question 3:
(a) The Venn diagrams in the answer space shows sets P and Q such that the universal set, ξ = P υ Q.
(b) The Venn diagrams in the answer space shows sets X and Y and Z, such that the universal set, ξ = X υ Y υ Z.
Shade the set (υ Z) ∩ Y.

Solution:

(a)

PQ means the intersection of the region P and the region Q.

(b)

• (X υ Z) means the union of the region X and the region Z.
• The region then intersects with region Y to give the result (X υ Z) ∩ Y.

Question 4:
The Venn diagrams in the answer space shows sets P, Q and R such that the universal set, ξ = P υ Q υ R
