What is the probability distribution of $M$, given $M=V*X/k$, where $X$ is Normal, $V$ is Exponential, $k$ constant?
Or, in the real world, the probability distribution of (Cost/k) where Cost=Price*Quantity, price Normal, quantity Exponential and k constant.
The distribution of estimated quantity (the actual quantity is unknown) will be the empirical distribution of Cost spread out (extended or shrunk) by different levels of $k$?
WolframAlpha (Mathematica) and MathWay both seem strangely obdurately in misunderstanding this elementary question, in every formulation....
