How is decision tree(DT) different from a risk breakdown structure(RBS)?
A. A DT helps the need for monetary reserves. An RBS doesn't

B. The terms mean the same type of graph used in project risk management.

C. A DT calculates EMV's for all branches, an RBS only for choosen ones.

D. An RBS calculates EMV's for all branches a DT only for choosen ones.

can you answer and explain? I selected C as answer and the correct answer was D.

This is from Oliver lehmann PMP question from Android app and I am posting for learning/understanding purpose only.

I posted this to oliver lehmann and he responded with a gif image and below lines for my understanding.

The example shows how all branches of the tree are set to "True", and for each chance "occurring", there is also a branch "not occurring". To complete the example, I added two risks with three chance options, occurring and badly occurring (pessimistic) with three-point estimation.

I hope this helps understand the RBS part of the question.
