Assume that the student
has a cup with 15 writing implements: 8 pencils, 5 ball
point pens, and 2 felt-tip pens.In how many ways can the selection be made if no more than one ball
point pen is selected?

"In how many ways can the selection be made if no more than one ball point pen is selected?"

Are the pencils all the same ? etc

Is one ball-point, 6 pencils and 2 felt-tips a "selection" ?
Is just one pencil a "selection" ?
You have to define what you mean by a selection.

• finite math -

I thought it over and I would do it this way:

the pencils can be taken in 9 ways, that is,
take none, 1,2,3,.. or 8 of them
the ball-point pens can be taken in 2 ways, none or 1
the felt-tips in 3 ways, none, one or both.
number of selections = 9(2)(3) or 54

But that would include the case of taking none at all, which would not be a selection,

so number of selections is 54-1 or

53 ways.

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.
