D) perfect information.

Question

Quizplus · Accepted Answer

Decision trees consist of branches that represent decision alternatives, with each branch leading to different possible outcomes or events. The nodes along the tree represent states of nature, which are events that may occur and affect the outcome of the decision. Therefore, option C accurately describes the structure of a decision tree. Options A and B are incorrect because decision trees do not involve varying branch angles or triangle probability nodes. Option D is incorrect because decision trees are used to depict decision-making under uncertainty, which implies imperfect or incomplete information.
