CEVAP:

Branch: The line connecting the nodes on a decision tree is called a branch. A branch is a single strategy that connects either two nodes or a node and an outcome.

Decision node: The decision node, represented in a square shape on the decision tree is a point from which two or more branches emerge. Each branch from a decision node represents a possible alternative to be chosen by the decision-maker.

Chance node: A chance node, represented in a circle shape on the decision tree, indicates that one of a finite number of states of nature is expected to occur at this point in the process.

Payoff: In decision analysis payoff refers to the consequence resulting from a specific combination of a decision alternative and a state of nature.
