WitrynaSo it is a empty set. Example : A = {0, 2, 4, 6, 8} Here set A has 5 elements and 0 is one of the element of the set. In above set A, if we find subset of set A, we write {0} as the subset of the set A. In this case it is not an empty set. It contains one element in it.

WitrynaAssuming that in your set theory it is consistent to talk about the universal set and it is { x: x = x }, then its complement is. { x: x ≠ x } so no set can belong to it. In other words, the complement of the universal set is the empty set. It's true that ∅ is a subset of any set, but this has no consequence on the fact above.
