Maybe. Amplitudes of (whatever) waves
satisfy linear equations. So, amplitudes
combine linearly when several paths are -
in principle - possible. On the contrary,
the intensity of waves, that is to say
the energy flux, is quadratic in the field
amplitudes. So, intensities do not combine
linearly. If we imagine there is a relation
between the energy flux and the number of
particles crossing a given (unit) area (this
can be the quantum principle, or the quantum
postulate) we also imagine there is a relation
between the energy flux - quadratic in the
field amplitudes - and the probability for
those particles crossing that (unit) area.
We can also imagine now there is only one
particle flying ....
