Consider the Bayesian Net below. All variables A, B, C, D are Boolean: A A false true P(A) 0.8 0.2 CAB P(C|A, B) false false false 0.9 false false true 0.5 false true false 0.6 false true true 0.1 true false false 0.1 true false true 0.5 true true false 0.4 true true true 0.9 I What is the probability of P(a, b, c, d)? C B B P(B) false 0.3 true 0.7 DDBC P(DIB, C) false false false 0.2 false false true 0.4 false true false 0.7 false true true 0.9 true false false 0.8 true false true 0.6 true true false 0.3 true true true 0.1 The notation indicates "false", e.g., a means that the value of a is false. Provide all calculations and explanation that show how you arrive at the answer.
