Which one of the following gives the members of the set A1 n B n C?
-
Φ
- {s}
- {t, u}
- {y, z}
The correct answer is: A
Explanation
A1 = Elements in the universal set but not in A = {s, w, x, y, z}
B = {r, s. t, u}
C = {t, u, v, w, x}
A1 n B n C = elements common to the three sets = none = empty set = Φ
