Probability Tree

Can someone please help me reword this it is due at 12:30 to night.

I like the idea of a probability tree. Even though I feel comfortable with the equation for the probability, having the visual representation is much more clear and easier to understand. I do feel that using it for something as simple as the probability of flipping a coin is not worthwhile unless you are looking to find the probability of finding what the odds of it being heads the twentieth time will be, and even then the equation may be. I do find the probability tree to be very useful for things like the example that was given in the book however of finding what the probability is of someone watching a commercial, or to relate this to another discussion we had on another post, what are the chances of finding the money behind one of three doors. Probability trees can be a very useful tool for me in the future.
