Is Gibbs free energy intensive or extensive?

Entropy says that any closed system will become more disordered over time. If there are only a small number of parts in the system (say 3), then there is 1 correct order (123), and 5 incorrect orders (132, 213, 231, 312, 321). If the system randomly changes order, there's still a good chance of it changing from a disordered state to an ordered state. That would make entropy wrong. However, in a system with billions of variables, the chance of returning to an ordered state is negligible. In a system like this, you can count on the rule of entropy. That's why entropy depends on the amount of parts in a system.
