Constellation of Bayes
Two overlapping circles share a single bright star — the joint event. Bayes' theorem is the gravity that pulls one circle through the other.
P(A | B) = P(A ∩ B) / P(B)확률

An atlas of probability concepts
Each tile is a small chart of the sky. Hover a tile to feel its bloom; let its illustration steady you while the idea unfolds.

Coin in Orbit
A single trial with two outcomes — the heartbeat of probability. Each toss a small revolution.

The Bell of Stars
Symmetry, falling away from the mean, two thin tails sliding into the night. The bell rings softly across populations.

Law of Large Numbers
A wandering trace finds its way home — toward the expected value, slowly, surely.

Constellation Chalice
An urn holds every possible outcome. Reach in — every draw is a small fate, every fate a small star.

Memoryless Stars
Each state forgets the past. Tomorrow depends only on today — a sequence of small starlit decisions.

Rare-event Stars
Rare lights flicker over fixed intervals — meteor showers, customer arrivals, radioactive decay.

Stars Becoming Bell
However ragged the start, the average always rounds itself into the bell — the deepest law in the night.

Concentric Uncertainty
Information is the surprise we feel. Entropy is the average surprise — the radius around the bright center where every outcome is equally likely.

Hover a star. Watch the threads of inheritance light up between theorems.
