I am working on a bayesian network problem and have been given the following table of data:
A | B | P(D=true | A,B)
---------------------------
F F 0.9
F T 0.6
T F 0.5
T T 0.1
If I wanted to determine the simple probability of D being true, how would I do this? I think that all of these events in the table are mutually exclusive, since A and B can only take on 1 value at a time. Would I just add all these probabilities to get P(D being true)?
Any help would be greatly appreciated!
