Position probability
= Position probability
{title2=$\Pr(x\in A)=\int_A|\psi|^2dx$}
For a normalized <wavefunction> $\psi(x)$, the probability of a <position measurement> lying in a measurable set $A$ is $\int_A|\psi(x)|^2dx$. It is a spatial-projection probability and differs from an <energy measurement> outcome probability.
