 P: 62 Hi everyone, Assume that we have an electron in the Coulomb field of a proton, whose wave function is specified. How can I find the probability of finding this electron in the ground state of the hydrogen atom? Thank you.
 Sci Advisor HW Helper P: 4,739 find the projection of that given wave function with the wave function of ground state for hydrogen.

Why do we do that? I couldn't understand the reason.

## probability of a wave function

It is the formalism of quantum mechanics?

Think of vectors in the plane, wavefuctions are vectors in Hilbert space.

The probability for state |a> to be in state |b> is given by: |<a|b>|^2
