Randomness
Randomness is unpredictability in individual results produced by a stated chance process.
Continue from this idea into connected AXIO math.
You can know the rules without knowing the next result.
Boundary: Closing your eyes and choosing from a stack is not automatically random if the stack order or choosing method makes some items easier to select.
What it means
You can know how the process works without knowing the next result. Short runs may look uneven or contain streaks. That does not by itself show the process is not random; long-run evidence and the method matter.
Remember it
You can know the rules without knowing the next result.
Example
A fair spinner has four equal sections. It may land on blue three times in a row. Each spin can still be random because the next result was not fixed by the previous streak.
Watch for
Closing your eyes and choosing from a stack is not automatically random if the stack order or choosing method makes some items easier to select.
Common mix-up
Random does not mean “messy” and does not require every short run to look balanced.
Exact meaning
A random process uses stated chance rules so that an individual outcome is not known in advance from the model, even though probabilities can describe stable patterns across many trials.
