Question

If A = {integers divisible by 2} and B = {integers}, what is A ∩ B?
Answer
{…-3, -2, -1, 0, 1, 2, 3 …}
{ }
{0}
{… -6, -4, -2, 0, 2, 4, 6 …}

Answer 1

intersection means what is in both

Answer 2

{...-6,-4,-2,0,2,4,6...}
these elements exists in both A and B
exists in A bcz all of them are divisble by 2
exists in B bcz all of them are integers
