I have a question about the formula for this problem:How many ways can an IRS auditor select 3 of 11 tax returns for an audit?

I know that it is 11! / 3!(11-3)! But apparently I am doing something wrong because my answer is not one of my choices. Am I using the wrong formula for this problem. Please any help will be appreciated. Thanks in advance
