* Assuming that the value of $S$ is known, list ''all'' independence relations between $T$ and other variables. Be sure to consider all of the cases in which the other variables in the model have known values and when they do not. | * Assuming that the value of $S$ is known, list ''all'' independence relations between $T$ and other variables.

+ | ''2015'': '''Note''': Assume that the CPTs in the model contain values such that if influence is possible between a pair of nodes -- given values of other variables in the model -- using the heuristics we have discussed, then conditional independence will not hold. Under that assumption, the structure of the graph will be sufficient to tell you that a given conditional independence statement is false. | ||
