You can put this solution on YOUR website! Suppose you own 30 cassette tapes and 20 CDs. If you wish to select 5 tapes and 3 CDs to take on a trip with you, in how many ways can you make your selection?
---------
# of ways to choose 5 tapes: 30C5
---
# of ways to choose 3 CD's: 20C3
---------------------
# of ways to choose 5 tapes and 3 CD's = 30C5 * 20C3 = 162456840 ways
