[Tree Dependent Distributions] Assume an undirected tree T obtained by the algorithm described in class for learning tree dependent distributions. We would like to show that the step of directing the tree by choosing an arbitrary node is okay. (a) State exactly what is meant by the statement the two directed trees obtained from T are the same .
