Which statement correctly explains the meaning of A ⊆ B?
Answer and explanation
Correct answer: Every element of A is in B.
The symbol A ⊆ B means that A is a subset of B. Formally, every element belonging to A must also belong to B. The sets may be equal, because the subset symbol allows equality, or A may be smaller than B. This statement is different from A ∈ B, which says that A itself is an element of B.
