Is there an amateur level book that talks about why QM depends on probability (assuming that is the actual teaching)?

The "why" of probability in quantum mechanics refers to the underlying reason behind the probabilistic nature of quantum systems. It is a fundamental question that has puzzled scientists for decades and has led to various interpretations of quantum mechanics.
In quantum mechanics, the behavior of particles is described by a mathematical framework called wave functions. These wave functions contain information about the probability of finding a particle in a certain location or having a certain property. Therefore, probability is a fundamental aspect of quantum mechanics and is used to make predictions about the behavior of particles.
In classical mechanics, determinism states that the future behavior of a system can be predicted with complete certainty based on its initial conditions. However, in quantum mechanics, this concept is replaced by probability due to the inherent uncertainty at the quantum level. This is due to the principles of superposition and measurement, which state that a particle can exist in multiple states simultaneously and can only be described probabilistically.
Measurement plays a crucial role in the probability of quantum systems. It is through measurement that the probabilistic nature of quantum systems is observed and confirmed. The act of measurement causes the wave function to collapse into a definite state, and the probability of obtaining a specific outcome is determined by the wave function at the time of measurement.
The probabilistic nature of quantum mechanics is typically only observed and relevant at the microscopic level. However, the behavior of individual quantum particles can be used to explain macroscopic phenomena through statistical methods. This means that while the probabilistic nature of quantum mechanics may not be directly observable in the macroscopic world, it still plays a crucial role in understanding and predicting macroscopic events.
