Question

If all the elements of set A are also elements of set​ B, then set A is​ a(n) _______ of set B.

Answer 1

Answer: subset

A ⊆ B

Step-by-step explanation:

Set A is a subset of set B, If and only if all the elements of set A are also elements of set B.

A subset is a set whose elements are all members of another set. The symbol "⊆" means "is a subset of". For example:

Set A: {1,2,3}

Set B: {0,1,2,3,4,7,8,}

Since all the elements of set A (1,2,3) are in set B. So

A⊆B.
