Question

If A = {positive integers divisible by 2} and B = {integers}, what is A ∩ B?

Answer 1

A = (2, 4, 6, 8...) and B = (1, 2,3, 4, 5, 6, 7, 8...)

A ∩ B = Terms that A has that B does not.

Answer 2

idk??

Answer 3

So the answer is (2, 4, 6, 8...)

The INTERSECTION of two sets is the set of elements which are in both sets.

For example: let A = (1,2,3) and B = (3,4,5). The INTERSECTION of A and B, written A ∩ B = (3).

Answer 4

It's basically asking you, in both the sets (2, 4, 6, 8) and (1, 2, 3, 4, 5, 6, 7, 8...) (Goes on forever) What will both the sets have in common? Well, the obvious choice is they have only terms divisible by 2 in common.
