Question

if A=1, 2,3,5,0 and AnB=2, 3 then A-B=?​

Answer 1

A = {1,2,3,5,0}

A ∩ B = { 2, 3 }

now we know that intersection operation on two sets gives us the common elements of both the sets.

A - B set will be the only elements unique to set A.

we know that A has 2 and 3 common with set B.

so A - B will be all elements of A except 2 and 3.

which is A - B = { 0 , 1 , 5 }
