How it is calculated
Each toss compares a random number from 0 to 1 with a threshold of 0,5. The generator comes from the browser. Earlier tosses do not change the next one.
Heads if the random number is < 0,5
Where the numbers come from
- How many flips
Example
Ten tosses rarely land exactly 5:5. The calculator shows the tally you actually got, not what “should” happen.
Questions
Can I use it to draw lots?
For settling a household argument, yes. A lottery that involves money needs written rules, not a browser page.
Why is the series not shown at 100 flips?
A long string is hard to read. Only the head and tail totals remain. Up to 40 tosses, the run is shown.
Does the coin have a memory?
No. Five heads in a row do not raise the chance of tails on the sixth toss.
