Probability Basics
Run an experiment lots of times and watch the results settle towards what theory predicts. Then build the full list of possible outcomes.
Coin, dice or spinner
Pick a device, then run some trials. The more trials you run, the closer the results usually get to the theoretical probability.
Device
Rename a section or change how many slices wide it is. Wider sections are more likely.
| Outcome | Frequency | Relative frequency | Theoretical |

Frequency of each outcome
Sample space builder
A sample space is every possible outcome, listed once. Add a second device and watch the list turn into a grid.
