Which of the following decision tree nodes have probability attached to their branches?
A.
Root node
B.
Event node
C.
End node
D.
Decision node
Explanation:
Event nodes represents the possible uncertain outcomes of a risky decision, with at least two
nodes to illustrate the positive and negative range of events. Probabilities are always attached to
the branches of event nodes.
Answer A is incorrect. Root node is the starting node in the decision tree, and it has no branches.
Answer D is incorrect. It represents the choice available to the decision maker, usually between a
risky choice and its non-risky counterpart. As it represents only the choices available to the
decision makers, hence probability is not attached to it.
