Total Casino

Total Casino is a tool for exploring probability with colored tokens. Start with a bowl of three red, two blue and one yellow token, or create your own. Name up to four color groups and edit their counts. Choose a group to see its chance on one draw, with the token counts, original fraction and reduced fraction shown together. Choose a first and second color to compare two ordered draws with and without replacement. Follow the multiplication and see how leaving the first token out changes the second chance. Read explanations of equal chances, draw order and impossible outcomes. Change the bowl and calculate again to explore different compositions at your own pace. Save bowl titles and compositions locally on your device, then load, edit or delete them. Draw choices and results stay in the current session in Total Casino.
