How this page works
The writing boxes below are yours. What you type stays in this browser, is saved here as you go, and is never sent to us or to your teacher. Hand the written work in the way your teacher asked for it.
The graded check at the bottom is the part that records to your teacher's gradebook.
Part B, from your handoutNot recorded
Your handout says these are the same items available here. Part A stays on paper.
Q1 · 3 points on the handout
Suppose you change chanceOfRain from 40 to 70 and rerun the 1000-day simulation. Predict how the rainy fraction changes, and explain how this single change lets you test a hypothesis without any real weather.
Q2 · 3 points on the handout
The chanceOfRain of 40 came from ONE weather station downtown, using ONLY last summer's data. Name one real-world element this excludes, and explain the bias it could introduce when the app is used across the whole city in winter.
Q3 · 2 points on the handout
ENRICHMENT: Give one real phenomenon where a rain-style simulation would be the RIGHT tool because the real experiment is impractical, and name which of the CED's reasons (too big, small, fast, slow, expensive, or dangerous) applies.
Q4 · 0 points on the handout
Next step: you traced this simulation by hand. Now head to the Topic 3.16 page and type and run the harder versions, where the computer checks a deterministic property of your simulation for you.

About the line in your handout
Your handout says this exercise is available online and auto-graded. The exercise IS here, and it is the same work in the same order, but the auto-graded half is not written for this topic yet. Nothing on this page is scored or sent to your teacher.
Hand this in the way your teacher asked for it. Topic 1.1 has its graded check today, and the rest follow.
