Question

Prove that set A intersect Set B is a sub set of set A
It is emergency.

Answer 1

Step-by-step explanation:

To prove :

SetA intersection Set B is a subset of set A

Proof:

Let A ={1,3,5,8,9}

B={2,5,8,9}

A intersection B = {5,8,9}

{5,8,9} which is a subset of set A

Answer 2

To Prove: (A ∩ B) ⊂ A

Let, A={a, b, c, d}

and,B={a}

So, ≫ A ∩ B={a}

Here, as,

{a} ⊂ A [ {a} is one of subset of A]

i.e., (A ∩ B) ⊂ A

Hence, proved.
