Easy Stats homework problem? How do I do it? (10 points for best answer!)?

In a box there are 23 light-bulbs, of which 10 are not working. We select 9 light-bulbs at random without replacement. What is the chance that 4 of the selected light-bulbs are not working? 

I've attempted this close to 10 times, and still can't figure it out! Thanks for helping

    10/23 aren't working, which is 43%. This means 13/23 are working, which is 57%.

    9/23 selected at random. Continue from here...
