(a) Consider the Bayesian network with the given conditional probabilities in Figure Q1a below: A B C A B T F T F T F 0.6 0.4 T 0.9 0.2 T 0.3 0.5 B F 0.1 0.8 F 0.7 0.5 Figure Q1a. The Bayesian network and the conditional probabilities What is the probability for variable C? The joint probability in terms of conditional probabilities is expressed as: P(B, A) = P(B| A)P(A).
