Please read the whole article in Decoded Science. "The Pitfall that Conditional Probability is Not Commutative" continues a series by highlighting a pitfall for unwary mathematicians.
Three Original Images for Conditional Probability
Other Articles
As I explain below in "An SEO Link Experiment Begins", I'm also providing one link to my reference material. In this situation, it happens that my only resource was "Conditional Probability" by Eric W Weisstein at MathWorld Wolfram.
Writing Tips
First, publish your original images where you along can claim copyright for them. Your blog is a good place!
Second, publish the caption with the image, such as my "image by Mike DeHaan".
Third, it's best to start the caption with key words you want to emphasize for your main article. Add the words "picture" or "image" to clarify that this reference is not a whole article, just another pretty picture. Finally, despite the way I do it, some wise people recommend that one omit the quotes ("). Personally, I prefer to use them, especially when the web editor does not handle italics or special fonts to set the caption apart from the main text.
An SEO Link Experiment Begins
"SEO" means to "Search Engine Optimization", which is a group of techniques aimed at placing one's articles higher in search engine results for the desired keywords.
In the middle of January, 2012, the PageRank for my Blog of Writing here on Weebly is '3'. So is my DeHaan Services site.
However, the Wolfram Mathworld site has PageRank '8'.
PageRank is a number from zero to ten, as far as I know, that indicates how authoritative a site or article is...compared to everything else on the Internet. Higher numbers are better. New sites are "unranked".
The experiment is to add one high page-rank reference link to my promotional articles. Let's see whether I can find a difference in the number of page-views for my publicity articles, and especially for the online magazine articles that I'm promoting.
I will also go back to a few older promotional articles, just to speed up the process.
