I need to learn how to solve the question. If it ends up with the answer fine, but I need to know how to solve this kind of question because I have a couple more questions like it and I actually want to learn.

The question:
Pretend you are drawing cards without replacement from the infamous "Iraq's Most Wanted" deck issued by the U.S. Military. If you are drawing from the full deck of 55 cards, what is the probability that you draw three cards, which end up being Saddam Hussein and his two sons.

(The order doesn't matter, its 3 out of 55). My question is for a question like this do I take 55 + 54 + 53 = 1:162 since with each card drawn without replacement the number of cards in the pool changes from 55 to 54 to 53 or how would I calculate it?

If the question were "you draw 30 cards and none of them were saddam hussein" how would something like that be solved? Same way? Explain.

Thanks!!

P.S. I'll give you full credit when I submit my assignment, as a "tutor" of sorts.
