確率サイコロ実験室

This math learning material allows you to visually observe the relationship between probability and ratios through repeated experiments with dice and coins.

By selecting the number of trials, the frequency and ratio of each outcome are reflected in a graph. You can observe how the results change as the number of trials increases, by changing the outcome you focus on or tracing the intermediate ratios. Dice and coins can be tested separately.

You can progress at your own pace by "predicting, testing, and comparing." No login is required.
