B ∪ A is the relationship between Set A and Set B.
We have two sets A and B.
We have to determine the relationship between set A and set B if A intersects B = B.
A set is a collection of elements, numbers or objects, represented within the curly brackets { }.
According to the question -
A ∩ B = B.
This means that the intersection of set A and set B is equal to B. This means common elements in both the set are same as the elements of set B. This can only happen when -
B ∪ A → B is the subset of A.
Hence, B ∪ A is the relationship between Set A and Set B.
