What is EPV

Can anybody please clarify what is EPV (expected path value). I came across a question in my PMP exam -


What is the difference between NPV and EPV.


Suruchi, PMP



 EPV(Expected Present Value) vs. NPV(Net Present Value) appear on my exam, please answers and clear explanation is required specially the risk and discounts associated with EPV and NPV respectively.




No expert on EPV, but ... I interpret anything with "expected" in it to have a probability factor. My conclusion -- NPV adjusted for risk. Btw, I passed PMP on 02/26 and had a qn on this topic.
