AI Thread Summary
The discussion centers on a project about using probability and statistics to predict the weather, initiated in a Precalculus class. The student expresses difficulty finding relevant information online regarding weather prediction through statistical methods. Suggestions are made to explore various websites that provide insights into weather forecasting, including explanations of the probability of rain and more complex statistical approaches. One participant humorously suggests a simple prediction method of assuming "no change" in weather. Overall, the conversation highlights the challenges of researching weather prediction techniques and the importance of reliable resources.

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? :)
 
I found this website http://www.cimms.ou.edu/~doswell/probability/Probability.html
But I don't think I would able to do it without learning sequence and series.
 
Regarding weather prediction -

Astronuc the web sites that you gave me were very helpfull thanks a lot!
 
I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks
Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
