Maybe we just don't understand the quantum variables yet, or maybe those variables exist in an as ye, undiscovered 12th dimension, cause I will stick to the belief of dynamical systems. (given all the positions and momentums of every particle and energy in existance, one could, theoretically(doesn't work in practice) predict the future).
IMHO though, if you flip a coin, over ten flips you will get a collection ofboth heads and tails but on a single toss, with an exact force applied and stuff (all variable accounted for) the coin would always and will always land on either heads or tails (it will only ever be one).
