The Pick Data Structure

A pick is a Markoff Chain. I am not a piack in Clarity. x is a b c and d is a list in Clarity. y is a b c or d is a pick in Clarity. x with a probabity of 50%. x is a half the time, b a quarter of the time, c or d. What does that mean? 50% of the time x is a 25% of the time x is b 12.5% of the time x is c 12.6% of the time x is d x is a b c and d is the list a b c and d all of the time.b That is an assertion. It can be checked by a background process. x is x all of the time x is y half of the time. That is an error or some sort, not quite a contradiction. I should learn more Prolog. -- QED
