Random Boolean Generator

Random Boolean Generator

Set a True probability from 0 through 100 percent and generate from 1 to 1,000 lowercase true or false lines.

At 0 percent every result is false; at 100 percent every result is true. At 70 percent, each independent draw has a 70 percent chance of true, but a short list need not contain exactly 70 percent true values.

The probability must be a finite number inside the stated range. Results are sampled independently with replacement and no balancing correction is applied.

Values are plain text rather than a JSON array, CSV column or spreadsheet Boolean cells. Copy them into the required format after generation.

Sampling stays in the browser and uses cryptographic random integers. The page has no seed, history, statistical test or guarantee of a particular observed ratio.
