Outcomes & Probability
by Anonymous
Roll two dice and flip coins to count outcomes with the multiplication rule and tree diagrams, then read off the probability of each sum out of 36.
About this app
An interactive middle-school math app for learning counting principles and probability. Explore the product rule by changing the number of dice and faces, visualize coin-flip outcomes with a tree diagram, and calculate the probability of target sums from two dice. Guided missions help learners discover patterns such as 2ⁿ outcomes and the 1/36 to 6/36 distribution of two-dice sums.
Use cases
- Middle-school students practicing outcomes and probability
- Teachers introducing the multiplication rule
- Learners exploring tree diagrams for coin tosses
