Probability wizard

About a year or so ago, there was a thread here about the need for a Probability Wizard. The collection of Wizards that I posted in that thread wasn't bad considering that it was written within the confines of PPL, but the new Probability Wizard is a much slicker tool in every respect.

For those of you who are interested in Stats, check it out. It's found in the Toolbox, Math, Probability, Prob. Wizard...

Take note of the Linked option in the soft menu. It allows you to indicate whether or not you want the left and right bounds to be linked together such that there are equal areas to the left and right of the bounds. This is a very useful feature for finding Critical Values. (But don't forget to turn Linked off when you don't want it or you will get very unexpected results.)

It looks like the visual representations have issues as the incorrect areas are shaded, but otherwise the Wizard looks great.
