1. probabilities

Five different CD-ROM games, Garble, Trapster, Zoom, Bungie, and Blast Em are offered as a promotion by Sugar Rush cereals. One game is randomly included with each box of cereal.
a) Determine the probability of getting all 5 games if 12 boxes are purchased.
b) explain the steps in your solution.
c) discuss any assumptions that you make in your analysis

I tried several different things for this q, but I didn't get the answer in the textbook for any of them. Their answer is 33/182.

(1/5)^12

1/5 x 1/4 x 1/3 x 1/2 x 1/1

I think this problem is a dependent event

3. ok? I don't understand the connection..

4. ok, so I tried something like this:

5/12 x 4/11 x 3/10 x 2/9 x 1/8

am I way off, or somewhere on the right track thinking..??
I have thought about this for a long time now and I still can't seem to get the answer they have in the textbook.. anyone know how they got it?
