Yes or No Calculator — Random Answer Generator
Type an optional question, then press Flip for a fair, random Yes or No. Each flip is a 50/50 coin toss — the donut chart tracks your running yes/no split across multiple flips.

How does this calculator work?
Draws a uniform random number and returns Yes if it is below 0.5, No otherwise — a perfect 50/50 coin flip every time. Each draw is independent (no memory of past results). The donut chart shows the running yes/no split across all flips in the current session.
Formula
How this is calculated
Each flip draws a uniform random number u in the range [0, 1) using your browser's pseudo-random generator. If u falls below 0.5 the answer is Yes; otherwise it is No. Because the threshold is exactly 0.5, every flip is a fair 50/50 coin toss — no bias toward either answer.
The donut chart accumulates every flip in the current session so you can see how close the observed yes/no split is to the theoretical 50/50. With just a few flips the observed proportion can vary widely; with many flips it will converge toward 50% by the law of large numbers.
Every draw is completely independent — a run of Yes answers does not make No more likely on the next flip. The question field is optional and has no effect on the randomisation; it simply frames the session for you.
Frequently asked questions
It uses your browser's pseudo-random number generator (Math.random()), which is seeded from hardware entropy and is more than adequate for casual decisions, games, and tie-breaking.
True randomness produces varying outcomes — the observed proportion converges toward 50% as the number of flips grows large (law of large numbers), but individual sessions will always show some imbalance.
No. The question field is just for context and has no effect on the random draw. Every flip is always a fair 50/50 regardless of what you type.
