Probability
by Anonymous
Spin spinners and roll dice to watch the experimental probability close in on the theoretical one, and count the outcomes behind each two-dice sum.
About this app
Probability is an interactive math learning app for exploring theoretical and experimental probability. Adjust a spinner’s total and winning slots to match target probabilities, roll a virtual die to compare relative frequency with the theoretical 1/6, and solve challenges about the number of ordered pairs that produce sums with two dice.
Use cases
- Middle school students learning probability
- Teachers demonstrating theoretical versus experimental probability
- Learners exploring ratios such as 1/2 and 1/4
- Students practicing two-dice outcome counting
Features
- Adjustable spinner with total and winning slot controls
- Missions for creating probabilities of 1/2, 1/4, 1, and 0
- Virtual die rolls in batches of 1, 10, or 100 with reset
- Experimental probability display compared with 1/6 and 16.7%
- Two-dice sum challenges with multiple-choice answers and streak tracking
