alleryWhich statement about the EMPTY SET ∅ is INCORRECT?
A∅ has zero elements, so n(∅) = 0
B∅ is equal to {0}
C∅ is a subset of every set
D∅ is denoted by ∅ or { }
Answer & Solution
Correct answer: B. ∅ is equal to {0}
{0} contains one element (the number zero) — it is NOT empty.
∅ contains no element at all.
∅ ⊂ S for every set S; n(∅) = 0; standard notation is ∅ or { }.
