ITPEC IP October 2023 Question 4
ITPEC IP October 2023 — Question 4 of 100
The shaded region consists of elements in B or C while excluding every part that is also in A. Start with the union B or C, which covers both lower circles including their overlap. Applying not A removes the two overlaps with A, including the central region shared by all three sets. The result is (not A) and (B or C).
Answer (b)
Why not others:
- (a) keeps only the overlap of B and C outside A, not the separate B-only and C-only areas
- (c) includes almost everything outside A, even points outside both B and C
- (d) includes all points because anything either lies outside A or can be included through the broad union
Key rule: Shading across either of two sets indicates OR; removing another set requires AND with its negation.
