Instead of studying, I made a little doodle. It only took five minutes at the most, but it was a little bit cute so I thought I'd scan and upload. The scan made the color pencil kind of funny looking and took away a lot of the shading though. @_@.

This was supposed to say:

What is the probability of drawing exactly two aces from a standard deck in three draws without replacement?
P(A1&A2&~A3) = P(A1)*P(A2|A1)*P(~A3|A1&A2)
P(A1&~A2&A3) = P(A1)*P(~A2|A1)*P(A3|A1&~A2)
P(~A1&A2&A3) = P(~A1)*P(A2|~A1)*P(A3|~A1&A2)

Would anyone like to help me out with this problem? I completely forgot how to do probability. =_=
