Finite Hw Problem: 5 pencils, 4 ball point pens, and 2 felt-tip pens.

[julia10103]

Assume that the student has a cup with 11 writing implements: 5 pencils, 4 ball point pens, and 2 felt-tip pens. (1) In how many ways can the student select 2 writing implements?



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

I cant figure the second part out!

Have you considered a different problem?

"no more than one" = "not both"

Don't always just stick with the given language. Recast the problem using some equivalent description.
