Experiment guide

Try throwing a die yourself:
Step 1 of 4
  • The die shows the last throw.
  • The event here is “a 6”: ✓ when it happened, ✗ when it did not.
  • The line is the relative frequency of a 6: the share of the throws that gave one, as the throws add up.
  • The more throws, the closer it stays to the dashed line – the probability, 16\displaystyle \frac{1}{6}.
  • With no event, each face gets its count and a bar as long as its share.
  • After many throws the six bars are almost equal: each face has the same probability, 16\displaystyle \frac{1}{6}.
  • Clear asks first: the throws cannot be brought back.
