Question

Prove that
A -B is a subset of A

​

Answer 1

LET US ASSUME

SET A = Universal Set

And SET B = {x:x is the set of all even natural number}

So,

Then A - B = Universal Set – {x:x is the set of all even natural number}

= {x:x is the set of all odd natural number}

So You Can See SET A – B = {x:x is the set of odd natural number} is Also A Subset of SET A.

Therefore A – B ⊂ SET A...
