Combinations and Statistics Question A bin with 100 parts contains 8 that are defective. A sample of 10 parts are obtained. How many samples contain exactly 1 defective part?

My answer was 10 as each defective part is mathematically indistinguishable from each other and the same for the non defective parts. Therefor, the defective part can occur in 10 different places in the sample leading to 10 different possible samples. I feel like the information before that was misleading. 

Edit: I want to clarify that I think the question was poorly worded and ambiguous which is why I am looking for clarification and maybe my interpretation was flawed.
Your answer is flawed because it doesn't take into account how many defective pieces there are. Also, you are not actually told that the defective pieces are indistinguishable. You could have a bin of 100 different parts, 8 of which are defective. 

To count the number of 10-piece samples that contain exactly 1 defective piece, you need to count how many ways there are to choose 1 defective piece, and how many ways there are to choose 9 non-defective pieces, and multiply those numbers together. You do not care what order these pieces are in, by the way. The samples don't have any ordering to them.
