If only the B region is shaded, how can it be represented in set notation?
Answer and explanation
Correct answer: A′ ∩ B
Only B consists of elements that are in B but not in A. The complement A′ represents elements outside A, and intersecting it with B gives A′ ∩ B. This is equivalent to B − A. A − B is only A, A ∩ B is the common region, and A ∪ B includes both sets. Hence option C is correct.
