The Bayes net below describes a scenario where a student's level of understanding of class material (U) is dependent on whether the student takes notes (TN) or is actively listening to class (L), which in turn influences whether the student excels in class or not (E). The specific Bayes net is defined in the diagram below along with the CPTs. Note that these are all binary variables. Pr(TN=true) Pr(L=true) 0.8 0.75 Take Listen Notes TN L Pr(U=trueITN,L) true true 0.99 Understand true false 0.4 false true 0.65 false false 0.1 U Pr(E=trueIU) true 0.9 Excel false 0.5 Given this Bayes net, what is the probability that the student excels in the class? In other words, compute Pr( E=true ). Your final answer should be a probability value
