Question

Set A = {100, 200, 300, 400, 500} and Set B = {100, 300, 500, 700}.

Determine the elements in A' ∩ B.

{700}
{200, 400}
{100, 200, 300, 400, 500, 700}
{100, 300, 500, 700}

Answer 1

The correct answer is {200, 400}

Answer 2

How so?

Answer 3

A" contains all integers from 101 to 700 excluding the elements in set A, so it includes 100, 300, 500, and 700.

The intersection A' ∩B retains only the elements common to both sets, which are 100, 300, 500, and 700.

Answer 4

So, the correct answer is: {100, 300, 500, 700}.

Answer 5

Oh I see, alright!
