The best way to learn about it (and anything mathematical) would be to try examples, not read about it.
Try this example:
You draw 5 cards from a standard deck of cards putting them back after looking at them. What is the probability of two of them being hearts?
Figure out what your n and r are and then figure out your p and q (Remember, there's 52 cards in a deck and 4 different suits.)
If you get stuck I'll try to help you out
