Question

Quizplus · Accepted Answer

The correct symbol is $\notin$ because $\varnothing _ { - } \varnothing$ suggests an operation or comparison between two empty sets, which is not standard notation. However, interpreting the intention as whether the empty set is an element of itself, the answer is that no set is an element of itself unless explicitly defined as such. The empty set $\varnothing$ does not contain any elements, including itself.

Indicate which symbol, ∈ or ∉ makes the statement true. \text { Indicate which symbol, } \in \text { or } \notin \text { makes the statement true. } Indicate which symbol, ∈ or ∈/ makes the statement true.
