Each learning path is one chapter: a guided route through a topic, one small course at a time. Pick a class to see its chapters in order.
Will it rain tomorrow? Which team will win the toss? Chance is everywhere, and mathematics can measure it. In this chapter you learn what an equally likely outcome is, find the probability of an event as a number between 0 and 1, use the complement, and work through problems with coins, dice, cards and coloured balls. Python tosses coins and rolls dice thousands of times so you can watch the long-run share settle near the theory.
