Capstone: Probability Everywhere

Step back and look at what you've built. A bell curve that nature draws again and again. A theorem that conjures order from chaos. Counts of rare events, memoryless chains, simulations by the million, the seduction of streaks, and the calculus of choice. Together these aren't a pile of formulas — they're a single language for reasoning under uncertainty, and once you speak it, you'll hear it everywhere: in the weather report, the doctor's office, the markets, and the machines that are reshaping our world.
