Probability of logical propositions



Hello,

Having briefly checked out Alexey Beshenov's logic.mac package (discussed 
here earlier: 
http://www.math.utexas.edu/pipermail/maxima/2008/010825.html), I started 
wondering how difficult it would be to implement probability theory rules 
(sum and product rule) to allow the calculation of probabilities of 
related logical propositions, Bayesian-style? I have absolutely no prior 
experience with Maxima and CAS, so I can't estimate whether it is a piece 
of cake or a big project, especially for someone who's already "been there 
done that".

Best regards,
Jan Ploski
