Videos Probability of Dependent Events and Probability of Depending Events 2 don't match up too well.

Might include http://www.khanacademy.org/video/getting-exactly-two-heads--combinatorics?playlist=Probability

and http://www.khanacademy.org/video/exactly-three-heads-in-five-flips?playlist=Probability

Also, might consider some new exercises on decision trees and a second set of exercises that match up with the videos mentioned.
