My Probability Lab

Build a weighted spinner from familiar choices, make a prediction, then run an experiment to see what really happens.

Set up the experiment

Scientist name

Spinner topic

Create the weighted spinner

Weight 1 gives one equal-sized share. A weight of 3 gives three shares.

Build your own with AI

Copy this beginner-friendly prompt into an AI assistant and ask it to explain each part:

Build me a mobile-friendly personalised probability experiment in one standalone HTML file. Let a parent create named spinner outcomes with emoji and integer weights, choose 10, 20 or 50 trials, and ask which outcome is most likely, least likely or whether all are equally likely. Draw an accurate weighted spinner, let a child predict before spinning, support single and five-spin trials, compare theoretical percentages with observed results, explain random variation, keep a recent history and save everything locally.
