What is the posterior probability distribution of A? What is the
prior probability of the observations?
There is only one factor that contains A, this represents P(A &g). We can get the probability of g is 0.360380144+ 0.149368656 =
0.50975.
We can then calculate the posterior distribution on A (to 3
significant digits):
P(a|g) = (0.360380144)/(0.50975) = 0.707
P(¬a | g) = (0.149368656 )/(0.50975) = 0.293
