Answer:
Set A is a subset of set B. It means that every element of set A should be present in set B.
Step-by-step 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}
