Probability is the language uncertainty speaks when it wants to be understood. A scatter of points becomes a curve. A series of outcomes becomes a law. Watch enough trials, and randomness itself becomes predictable.
Normal Distribution
The bell curve emerges whenever independent random variables sum together. It is the shape of inevitability.
Poisson Process
Events scattered in time like stars appearing at dusk. Each one independent. The rate: constant and patient.
Random Walk
Each step a coin flip. Yet the path, observed from far enough away, traces the signature of diffusion itself.
As n approaches infinity, the sample mean converges to the true mean. Chaos becomes certainty.
