Probability

Probability is the share of the outcomes that count, and conditioning means changing which outcomes are in the room.

Before this leaf: Counting, Exponentials and logarithms.
This leaf feeds: Statistics and data, Linear algebra.
Objects you will meet again: the dial, the two towns, the fifteen.

Lessons, notes and demos

One row per lesson, in the order the leaf builds up. Each lesson holds its notes, its demos and its challenges on one page. A demo link opens the lesson at that demo.

This leaf is planned. Its lessons are being designed now, and each one appears here when it is built. The strip above shows its planned length.

The two towns are a Markov chain, so this leaf and Linear Algebra page 18 describe one object from two sides.

Glossary

Every new word from this leaf appears here, with one sentence and the lesson that introduces it.
