Age 15Explain it to a 15-year-oldConnect it to the formula
Flip an animated virtual coin and get a fair heads-or-tails result instantly. Each flip uses the browser's cryptographic random-number source. The animation and result remain entirely on this device. Change one input or choice at a time and compare the result to see which part of the rule it controls.
CollegeExplain it at college levelState the model precisely
The browser uses its local random source and the selected sampling or allocation rule. Each flip uses the browser's cryptographic random-number source. The animation and result remain entirely on this device. Entries and results remain in this browser. Important results should still be checked against the records, standards, or rules that govern the real situation.
How this tool works
Each flip uses the browser's cryptographic random-number source. The animation and result remain entirely on this device.
Privacy and limitations
Your entries and results stay in this browser. Check important results against the rules, records or systems that govern your situation.
