Hello everyone !
I would like to know if prob. theory is critical to learning Qm !
Yes, you definitely need to know the fundamentals of classical probability theory and statistics. Most 'mathematical methods' books have a chapter or two that'll provide you with the requisite background. For example, chapters 30 and 31 of Riley et al.'s "Mathematical Methods for Physics and Engineering" are quite good.
Yes - but only basic probability theory your likely learned at HS or an introductory subject at uni.
That said if you want to progress to higher levels in QM foundations you need some rather advanced knowledge:
Thank You !!
