Consider a network of the following type. A variable A, that is binary,
0:00:05.568,0:00:10.640
connects to three variables X1, X2, and X3 that are also
0:00:10.640,0:00:15.529
binary. The probability of A is 0.5, and
0:00:15.529,0:00:20.516
for all variable Xi we have the probability of Xi
0:00:20.516,0:00:25.750
given A is 0.2, and the probability of Xi given
0:00:25.750,0:00:29.370
knot A equals 0.6. I would like to
0:00:29.370,0:00:31.800
know from you the probability of A, given that
0:00:31.800,0:00:37.520
we observe X1, X2, and knot X3.
0:00:37.520,0:00:42.000
Notice that these variables over here are conditionally independent, given A.
