Re: Random Variables

Hi;

Okay! Very good.

Nice example, not only informative but mouth watering also.

In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

All good.  smile

You might consider a link from Variance on the third page to your Standard Deviation and Variance page.

Re: Random Variables

Hi MathsIsFun,

They're good!
You may consider adding a few lines about central moments, and tell that variance is one of those.
