Both answers have exactly the same 50% chance every time. Three Yes answers in a row has a probability of 12.5%, and over three presses at least one Yes appears 87.5% of the time.
The browser’s cryptographically secure generator selects 0 or 1, which maps to the two answers. Earlier answers have no effect on the next one, and the result is shown immediately rather than stored.
This is a casual decision aid, not a substitute for judgement. Do not use it for medical, financial, legal or safety decisions, nor for official drawings, which may require documented procedures, supervision or certified systems rather than a browser tool.
Press the button and the tool returns Yes or No. Internally the browser’s cryptographically secure generator selects 0 or 1, so both answers have exactly the same 50% chance every time. Earlier answers have no effect: three Yes answers in a row do not make No more likely next. The answer is shown immediately and not stored, which makes the tool convenient for light decisions such as who picks the film, which of two lunch spots to try or whether to take the stairs.
Runs of the same answer are more common than intuition suggests. Three Yes answers in a row has a probability of 12.5%, and five No answers in a row happens about 3.13% of the time. Over three presses, at least one Yes appears 87.5% of the time. If you are testing whether the generator feels fair, look at many results together rather than a short streak, or use the Coin Flip tool, which can run thousands of trials at once and show the totals.
A random answer is useful when both options are genuinely acceptable and the cost of deciding is higher than the difference between them. Some people also use it to reveal a preference: if you feel disappointed by the answer, that feeling is information. Do not use it for medical, financial, legal or safety decisions, and do not use it for official drawings, which may require documented procedures, supervision or certified systems rather than a browser tool.

No, runs are more common than intuition suggests. Three Yes answers in a row happens 12.5% of the time and five No answers in a row about 3.13%. To judge fairness, look at many results together, or use the Coin Flip tool, which runs thousands of trials at once and shows the totals.
When both options are genuinely acceptable and deciding costs more than the difference between them — who picks the film, which of two lunch spots to try, whether to take the stairs. The answer saves the deliberation, not the thinking.
Often, yes. If you feel disappointed by the answer, that feeling is information worth acting on. Some people use the tool exactly that way: not to obey the result, but to notice their reaction to it.
