🎲 Probability: how likely is it?

Unit 2 · Algebra & data · 10 min

Probability = favourable outcomes ÷ all possible outcomes, between 0 (impossible) and 1 (certain). A coin lands heads with probability 1/2; a die shows 6 with probability 1/6. The more trials you run, the closer results get to the theory.

Words in this lesson

• 概率 (gàilǜ) — probability
• 骰子 (shǎizi) — die / dice

Project: Flip a coin 50 times, count heads, compute the fraction and compare it with 1/2.
