About This Tool
This tool simulates flipping a fair coin, returning heads or tails with equal probability on each flip. It is the simplest way to settle a two-way decision or make an unbiased binary choice when you have no reason to favour either outcome.
Each flip is independent, so a run of several heads does not make tails more likely on the next flip, a point people often get wrong. Some versions let you flip many coins at once and tally the results, which makes the tool a small demonstration of probability as the counts even out over many flips.
The gambler's fallacy lurks here: a run of heads does not make tails more likely on the next flip, because each flip is independent. Over many flips the proportion of heads and tails tends toward equal, but that convergence works through the sheer number of trials, not by any correction of past results.
How to Use It
- Flip the coin.
- See whether it lands heads or tails.
- Flip repeatedly, or flip several at once, to settle a choice or watch probability at work.
