SequenceProbability & StatisticsGraphing
This example demonstrates the distribution of sums when rolling one, two, or three standard dice. It involves core math concepts like probability & statistics, random variables, and bar charts. Constructed using GeoGebra commands/objects such as Sequence, SelectedIndex, If, and BarChart. Suitable for high school students learning probability statistics or for classroom demonstrations.

GeoGebra Commands & Parameters

  1. Sequence(Element[freq, k], k, 1, (6 * dice) + 1) → freq2
  2. Sequence(Element[freq2, k] / n, k, 1, Length[freq2]) → relFreq
  3. SelectedIndex(graphMenu) → graphType
  4. If(n ≟ 0, 0, Max[freq]) → fMax
  5. Sequence(k - 1, k, 1, (6 * dice) + 1) → diceSum
  6. BarChart(diceSum, relFreq) → relFreqChart
  7. If(n ≟ 0, 0, Max[relFreq]) → relMax
  8. BarChart(diceSum, freq2) → freqChart
  9. Sequence(Text["" + (Element[relFreq, k]), (k - 1.3, Element[relFreq, k] + step)], k, 1, Length[relFreq]) → lbl2
  10. Sequence(If[Element[freq2, k] > 0, Text["" + (Element[freq2, k]), (k - 1.2, Element[freq2, k] + step)]], k, 1, Length[freq2]) → lbl
