Assume that the student has a cup with 9 writing implements: 4 pencils, 3 ball point pens, and 2 felt-tip pens. Students will select 5 writing implements. In how many ways can the selection be made if no more than one ball point pen is selected?

I don't know the answer but i know the answer is not 53. Not all info was givin to complete the problem. It should have read that they student will select 5 writing implements. How many ways if only one ball poin at selected.
