the phrase 'she picks' should be 'she pick'.
Just exactly does she do? Pick names from the hat, and in turn places them in a linear arrangement on the table?
This can produce 14! different orders of distinct names.

The answer that I provided is "14!" It is pronounced "fourteen factorial."
In mathematics, the ! symbol following a positive integer means 'the product of this number and all lesser integers, until the last number is 1'. Example: 3! means three times two times one, i.e. 6.
I stand by my comment implying that the problem was imperfectly written; we see far too much of this now that Common Core has crept into the mathematics curriculum.

Here's the deal: the teacher owes it to EXPLAIN how the question's answer comes about, so that the students can understand. That is, essentially, the job description. It MUST be discussed (and I would like to see it, too).
The explanation needs to include a rock-solid clear understanding of exactly what is intended, and then the method of solution. That's how we learn.
