As I began to write my Decoded Science article, "An Introduction to Conditional Probability in Mathematics", I wanted to achieve two online writing tasks.
First, I had to test the HTML for the "is an element of" symbol. Second, I wished to lay claim to my original "artwork" based on a spreadsheet I developed.
The Element Symbol in HTML
I Hereby Claim Original Artwork
As always, I also promote my article in DeHaan Services ("Introducing the Math of Conditional Probability") and in my Xanga blog ("Starting with Conditional Probability").
(Updated 2012-01-17) As I explain in "Preview of Non-Commutative Conditional Probability", I will also include a link to one article that I used for reference:
Weisstein, Eric W. "Conditional Probability". MathWorld--A Wolfram Web Resource.
