So my probability and stat knowledge is pathetically weak. I'm a Junior physics/math dual major and I'm going to be taking statistical mechanics and some other higher level physics courses next semester where I would really like to brush up on my probability and statistics. I really think I need a refresher starting from the ground up - any suggestions on books or good websites for this? I don't need a huge thorough introduction - something more dense and meant for a higher-level reader as opposed to a freshmen or highschool student would be better. Thanks.
