Probability theory 1.3

Quantum probability is almost the same as classical probability.

The only difference is that while classical probability is due to ignorance, quantum probability is due to superposition of eigenstates of the universal wave function and the ignorance of its details. We ignore the microstate details of the measuring-device/observer.

If we know all the details of the universal wave function, we will be able to predict what the final wave function will be. The final wave function will still be a superposition of a lot of different eigenstates. There is no real wave function collapse.
