Decision trees use nodes to represent decision points and branches to represent possible outcomes of decisions. Time does not necessarily have a set direction in a decision tree. The shapes used in a decision tree can vary, but circles are commonly used to represent chance nodes, triangles to represent decision nodes, and ovals to represent end nodes. The probabilities of outcomes are typically displayed on or beneath the end nodes. Therefore, the statement that is true concerning decision tree conventions is that nodes represent points in time (choice C).
