3. (Pearl's Message Passing Algorithm) Starting with the tree network shown in Figure 3 below, first initialize the network with Pearl's Algorithm. Then, compute the probabilities when C is initialized to c₁. P(b₁|a1) = 0.33 P(b₁|a₂) = 0.6 B P(a₁) = 0.5 A E P(ei | c₁) = 0.75 P(e1 | c₂) = 0.45 P(c1|a1) = 0.13 P(c₁ | ₂) 0.005 Figure 3: Diagnostic Network. D P(d₁ | ₁) = 0.4 P(d₁ | c₂) = 0.2 3.
