The link between simple probability and expected frequency is explored. The idea of risk is investigated and its impact on life.
Part ofMathsNumeracy
You can estimate probabilities from an experiment. These are sometimes called relative frequencies.
For example, in an experiment where a drawing pin was dropped \(1000\) times:
So the relative frequency of the drawing pin landing up is:
The number of times this outcome occurs (pin up) ÷ total number of outcomes (or trials)
\(= \frac{{279}}{{1000}}\,or\,0.279\,or\,27.9\%\)
