In dealing with solutions to the Schroedinger equation, I have come across the so-called expansion coefficients (c(adsbygoogle = window.adsbygoogle || []).push({}); n). I have read that the square of the coefficient is the probability density of an allowed value of E.

How is there a probability of any given value of E? I know that in a stationary state, there are definite values of E, so how is there any probability involved?
