I know the difference between the expectation value and probability density, but how do you calculate the probability density of an observable other than position? For position, the probability of the particle being in a particular spot is given by [itex]|\Psi|^2[/itex], which is the probability density, and the average of all those probabilities is given by [itex]\int \Psi^*x\Psi[/itex] correct?(adsbygoogle = window.adsbygoogle || []).push({});

Now for all the other observables (momentum, energy, etc...) the expectation values are straight foward, but how do I calculate the probability densities?

Thanks
