Does "random" have different meaning in classical physic from SR, GR or QM? What is the difference between random, deterministic and probabilistic? Is probabilistic either random-probabilistic or deterministic-probabilistic, or is probabilistic a truly separate category on its own? If we flip a coin 100,000 times and the number of heads match the number of tails 50-50% every time +/- some tiny variation, then how's that random outcome? Wouldn't it be truly random if we could flip 90% heads at one go and then 20% heads in another go just as easy, and just as easily as 40% heads, 1%, or 72%?
