Probability Resources

This page contains a tool for collecting experimental data and a number of problems, which all include interactivities. The interactivities are designed to enable rapid collection of experimental data so the focus in the lesson is on discussion of what the data shows and on finding theoretical probabilities to help support conjectures.

Data collection tool
This interactivity allows you to record successful and unsuccessful outcomes from an experiment
Data can be displayed as a graph or a table. Data from the table can be copied and pasted into a spreadsheet for further analysis.

Interactive Spinners
This problem invites you to explore probabilities of outcomes related to two independent events.

Flippin disks
Use the simulation in this problem to generates lots of experimental data quickly, freeing time to focus on making predictions and justifying them.

Cosy Corner
This problem offers an opportunity to explore experimental and theoretical probabilities. The simulation generates lots of experimental data quickly, freeing time to focus on predictions, analysis and justifications. Systematic approaches to listing all possibilities are helpful.

Two's Company
This problem continues the theme of the above two problems, offering an opportunity to explore and discuss two types of probability: experimental and theoretical. The theoretical probability being found by listing all possibilities. The simulation generates lots of experimental data so you can focus on predictions, analysis and justifications.

The Better Bet
This problem explores two situations asking you to decide which is the "better bet". Experimental outcomes can indicate a hypothesis which can then be tested using theoretical probabilities.
