A small change to Homework 4--Question V.E

[Subbarao Kambhampati <rao@asu.edu>]

I made a change to question V.E so that it is closer to what I discussed
in the bayes net inference class. Here is the new version of the
question. The online version of homework 4 now reflects this new
version.

Part E.[8pt] I am changing this question to make it more in line with
the material we actually did on Nov 16t. 
We just found that there the slurpees at Apus’s place have
liquefied. We also found out, from reliable sources, that the batch of
heavy water they are using at the reactor is INDEED low quality one.
Compute the probability distribution on Homer glowing in the dark. Use
the enumeration method—as discussed on Friday’s class—to compute this
probability (notice that this involves marginalization and
normalization). [If you want to be sure, You can check your answer by
plugging this network in the bayesnet tool and doing the query). 
(previously, it was “What is the numerical probability that Homer glows
in the dark and there is low-quality heavy water in the plant and there
is inferior-quality plutonium in the plant, given that we know that
core-meltdown has occurred? “—I would request that you do the new
version)
