What happens when two piles of circles—some colored, some not—are combined? What will the percent of colored circles in the final mixture be?
Choose the Mode, and then follow the instructions in red. In Exploration mode, you can experiment with piles of various size and percent colored to see what happens when the piles are combined. In the other modes, you will be asked to solve a specific problem:
The Combine! button causes the piles to mix, and you will see the result. The Uncombine button will return you to the two original piles.
The Next Question button clears all your work and displays a new problem. In Exploration mode, this button works like a Reset button, clearing all circles from both piles.
In Exploration mode, add some circles to Pile A and to Pile B. Color some of the circles in each pile, then combine the piles.
