Question

Let S = set of points inside the square, T = the set of points inside the triangle and C = the set of points inside the circle. If the triangle and circle intersect each other and are contained in a square. Then

A. S ∩ T ∩ C = ϕ
B. S ∪ T ∪ C = C
C. S ∪ T ∪ C = S
D. S ∪ T = S ∩ C

Answer 1

C. S ∪ T ∪ C = S

Given: S = set of points inside the square, T = the set of points inside the triangle and C = the set of points inside the circle

Since, the triangle and circle intersect each other and are contained in a square.

Clearly, S ∪ T ∪ C = S
