Wow. Thanks to Natalya I found the CODAP Plugins. I am getting used to the set up for the Sampler and am thinking about how I can use the Random Number Generator. It appears that the Sampler is drawing with replacement. Is there a way to change this to without replacement? I like how the spinner will merge like items in the mixer and also the Parent Visibility toggle in the Eye menu. Still working on how the Collector works. That is not comming to me through exploration this morning.
I did have a problem with the Normal Distribution Sampler plugin. This did not work in either Chrome or Firefox on my Windows 7 PC.
Cheers
