In my Precalcules class this month being the end of the school year our teacher told us that we have to do this project based on probability. And I was told to pick a topic that is an interest's me. I thougt this was going to be easy so I choose the weather predicting project. Our teacher told us that we have to do a reasearch today and we were going to diuscuss this in class. I search at google I don't know why when I searched "using satistics and probablity to predict the wather" I did not get not much of an info. So if you would be so help full to help me out with the web sites that might provide me some information that would be really greate. Thanks in advance!

I have heard it claimed that you can do a better job of predicting the weather, then the weather man, simply by predicting, "No change". That is, that the weather will be the same tomorrow as it is today.

I don't now, maybe you can use that, since you are looking at statistics.

How about dropping a needle (repeatedly) onto a ruled sheet of paper and using the probability of the needle crossing a line to estimate $\pi$? :)
