Question: You are given the following conditional distributions that connect the binary variables W, X, Y , Z: Which of the Bayes nets in Figure S13.17

You are given the following conditional distributions that connect the binary variables W, X, Y , Z: 

X|W|P(W|X)||XY| P(YX) |ZW|P(W|Z) 0.4 00 0.3 01 0.7 10 0.1 11 0.9

Which of the Bayes nets in Figure S13.17 can represent a joint distribution that is consistent with these conditional distributions? Of those, which are minimal, in the sense that no edge can be removed while retaining the property?
