Question

set builder form of A-B

Answer 1

Set builder form of A-B
= { x : x belongs to A and x doesn't belongs to B }

:)

Answer 2

Answer:

Therefore, The set builder form of A ∩ B is given by : A ∩ B = { x : x ∈ A and x ∈ B }

Step-by-step explanation:

The set A ∩ B  contains all those elements which are both present in the set A and in the set B.

Let x be any element present in the set A ∩ B then x is present in the set A  and also present in set B

So, A ∩ B will contain all a and b.

The set builder form of A ∩ B is same as the set notation or set representation form of A ∩ B

Therefore, The set builder form of A ∩ B is given by : A ∩ B = { x : x ∈ A and x ∈ B }
