I got stuck in my computer course question, please help!!1

In a search engine using the "Boolean conjunction" model, suppose:
(a) searching _information_ returns 10000 pages;
(b) searching _information literacy_ returns 2000 pages; and
(c) searching _literacy_ returns 8000 pages.

How many pages would be returned if we search _information OR literacy_?

If I understand it correctly, it would be 16000, right? 10000 in information plus 8000 in literacy. But there's an overlap of 2000 that are both information and literacy. So some are counted twice.
