# Probability in Quantum Mechanics: General

How do I find the most probable value of position of a (non-Gaussian) wave function? Is it the same value as the expectation value of the position? And is it true that the most probable value of position is equal to the mean for a Gaussian?

• So if I have to find the most probable position, then I need to find the derivative of the function and equate it to $0$? How about for most probable momentum? – Artemisia Nov 22 '13 at 16:10
