This app visually demonstrates conditional probabilities by allowing users to manipulate the probabilities of three events, $A$, $B$, and $C$, through sliders. Rectangles representing each event adjust in length and can be positioned to overlap or separate, visually illustrating the impact on their intersections, unions, and conditional relationships, with changes reflected in a graph of relative frequencies.
Drag the containers or use the sliders to change the probability of each event. Then make it rain! Observe the relative frequency histogram as the rain falls.
