In theoretical probability, the probability is determined by an assumed model (for example, the normal distribution). (compare with empirical probability)
As the number of times that the experiment is conducted increases, the experimental probability will near the theoretical probability - unless there is a problem with the theoretical model.
Probability model
The Gaussian probability density distribution (pdf) is referred to as the Normal distribution. The Gaussian model results in a Gaussian pdf. Interesting, it didn't come from Gauss, but de Moivre, one of the greatest mathematicians of the 18th century, at least in my opinion. See related links.

The Electron Cloud model
Electron Cloud Model.
The current model of an atom is called the Bohr model.
Pennsylvania
The Bohr Model, and its the basis of quantum theory
we can know where the element is .
they aren't the same. the current atomic model has the electrons moving freely in the atomic cloud while the bohr model has the electrons in a set orbit.
The most commonly seen atomic theory is an amalgamation of the Rutherford and Bohr models, and therefore referred to a the Rutherford-Bohr model(1913) The most modern one is a model formed from theories by Werner Heisenberg and Ernest Schrodinger as well as others and is referred to as the Atomic orbital model(1927), but has been greatly improved on since then
the wave mechanical model is the most current form of the atom. it is based on the probability of where electrons are going to be at a point in time. on diagrams it appears as a cloud around the nucleus.
A dense nucleus of protons and neutrons surrounded by electron clouds of different shapes and sizes.
The electron cloud model best describes the organization of electrons around the nucleus of an atom.
