We consider the following Bayesian network. We assume that all variables are binary. A B > V D We assume that Pla) = 0.2, P(b) = 0.8 Plcla,b)=0.7, Plc-a,b)=0.3, Plca, -b)=0.6, Plc -a, -b)=0.2 P(db) = 0.9, Pld -b) = 0.8 Calculate the following probabilities (keep only four decimal values for all probabilities). Note: you will use the proportion sign in your answer. Please copy it into your formula in the following form. 1. Pb-a.c) 2. P(b|c-d) We consider the following Bayesian network.
