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 current atomic model is called the quantum mechanical model. It is named that because it incorporates the principles of quantum mechanics to describe the behavior of electrons in atoms, including their wave-like properties and probability distributions.
The current atomic model is called the electron cloud model because it describes electrons as having both particle-like and wave-like characteristics, and they are found in regions of high probability known as electron clouds surrounding the nucleus of an atom. This model replaces the older concept of electrons orbiting the nucleus in fixed paths.
The Electron Cloud model
The quantum mechanical model of the atom, also known as the electron cloud model, shows electrons as existing in certain regions of space called orbitals. These orbitals represent the probability of finding an electron in a specific location around the nucleus.

Dalton's atomic model was often referred to as the "Billiard Ball Model" because he envisioned atoms as solid, indivisible spheres similar to billiard balls.
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 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.
The Schrödinger atomic model is known as the Quantum Mechanical Model or the Wave Mechanical Model. It describes electrons in atoms as standing waves guided by probability equations rather than fixed circular orbits.

The atomic model used today, known as the quantum mechanical model, incorporates the principles of quantum mechanics including the concept of electron clouds and probability distributions of electron locations, while Bohr's model focused on specific orbits for electrons. The quantum mechanical model provides a more accurate description of electron behavior and allows for a better understanding of the complexities of atomic structure.
