So funktioniert es

  1. 1

    Enter the probability of the event occurring as a percentage.

  2. 2

    Subtract that value from 100.

  3. 3

    The result is the probability that the event does not occur.

100 - event_probability

Häufig gestellte Fragen

What does complementary probability mean?

It is the probability that an event does not happen, equal to 1 minus the event probability.

Can I enter a probability greater than 100%?

No, probabilities must be between 0% and 100%.

Formeln

Die Mathematik hinter diesem Rechner, aufgeschrieben, damit Sie das Ergebnis überprüfen können.

Complementary rule

P(not A) = 1 - P(A)

The probability of the complement is one minus the probability of the event.

Example:

Input: P(A) = 0.30

Calculation: 1 - 0.30

Result: 0.70

Anwendungsfälle im Alltag

Wo diese Berechnung im täglichen Leben vorkommt.

Quality control

Estimate the chance a product is not defective given the defect rate.

Example: Defect rate 2% → 98% non-defective.

Risk assessment

Find the probability of no failure when failure probability is known.

Example: Failure 5% → 95% no failure.

Tipps und häufige Fehler

Tips

  • Always express probabilities as percentages or decimals consistently.
  • The complement of an event includes all other possible outcomes.
  • Check that your input is between 0 and 100.

Common Mistakes to Avoid

  • Forgetting to subtract from 100 when using percentages.
  • Using decimals instead of percentages without converting.
  • Assuming complementary probability is the same as odds.

Annahmen und Einschränkungen

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
