# Probability in Quantum Mechanics

Do you need to take a probability/statistics course for Quantum Mechanics, or is the probability in quantum mechanics so rudimentary that you can just learn it along the way? I'm in doubt as to whether I should take the course or not, is it needed? What probability is actually in QM?

Arithmetic mean, median, mode, sample & population variance, standard deviation, discrete and continuous random variables, binomial, poisson and gaussiand distribution and finally the expected value.

If you would like to add things I need which aren't listed, that would be wonderful. I'd hate taking the course knowing almost everything I need apart from a couple of things.

The probability theory you need to start studying QM is very rudimentary. You need to know what a probability distribution is, the concept of normalization and mean (expectation value). That's about it. When I studied it at Uni, the physics lecturers briefly introduced the concepts for people who hadn't studied stats. It can't have taken more than half an hour to describe.

So you would say I'm set already? This is my current knowledge of statistics/probability: Arithmetic mean, median, mode, sample & population variance, standard deviation, discrete and continuous random variables, binomial, poisson and gaussiand distribution and finally the expected value.

That's more than enough knowledge of stats to learn QM!
