Question

Describe the relationship between the two sets A and B if A ⊆ B. (No picture is provided in the question)

Answer 1

Set A is a subset of set B. It means that every element of set A should be present in set B.

Explanation:

A ⊆ B

Set A is a subset of set B. It means that every element of set A should be present in set B.

i.e for all a ∈ A then a ∈ B

Example:

Let set A = {1,2,3}

and B = { 1,2,3,4,5,6}

then A ⊆ B because every element in set A {1,2,3} is also present in set B {1,2,3,4,5,6}
