(27S) Probability Formulas

[Dave Britten]

I'm really impressed with how capable this 27S is so far. For a "non-programmable" algebraic, it can sure do a heck of a lot. I might even be able to get it to do quadratic regression with enough solver tricks.

I'll add some more fleshed-out examples; these are pretty short formulas, but it's always reassuring to know you're getting the expected results.
