Disclaimer: I am not sure if this should be in MSE or PSE, I will post it here for now.
Usually it is stated that there is a $50$% chance a coin will be heads and $50$% if it is tails. But couldn't you technically know what face the coin will land on if you know the force acting on the coin, the height it is from the ground, the mass of the coin, and the angle the coin is positioned at rest? If not then Classical Physics would be probabilistic?
