Please find the question in the attachment and give me more details about the given answer. I failed to understand when the question is about combinations and the formula is n!/k!(n-k)!, why the formula is reversed in the explanation stem. Also, I could not specified answer "105" either ways. Thank you in advance!

Couple notes:
1. Don't post attachments - make an effort to post the actual question if you have one, that way, we don't have to waste our time downloading and opening the attachment.
2. Search. Did it strike you that perhaps this questions has been discussed and has a great explanation so you are not wasting other people's time?

P.S. This looks like it has been taken from the Flashcards, you can post the question there instead: gmat-flashcards-108651.html?fl=menu
