Count decision-tree outcomes

A full decision tree asks three independent yes-or-no questions along every path. How many distinct answer paths are possible?

Problem decomposition map

Smaller answerable questions must reconnect to the target

  1. TargetDefine success
  2. DivideCreate subquestions
  3. DependOrder prerequisites
  4. BranchApply stopping rules
  5. AnswerGather branch evidence
  6. RecombineResolve the main question

Distinct subquestions, explicit dependencies, and stopping rules keep branches useful and prevent analysis from drifting.
