I'm really new to the concept of quantum mechanics

[badamann]

From what I've gathered about quantum mechanics, it's based on probability, correct? (Yes, it's true that I know next to NOTHING about this subject) Could someone explain to me how we've come to discover this and how it contradicts classical mechanics?
