Answer

Explanation:

Step1: Definición de probabilidad experimental

La probabilidad experimental de un evento en un conjunto de datos es el número de veces que el evento ocurre dividido por el número total de observaciones.

Step2: Identificar el número total de observaciones

El número total de personas (observaciones) es $n = 20$.

Step3: Calcular las probabilidades reales para cada grupo

  • Para el grupo 1 - 3: Hay $2 + 4+ 3=9$ valores. La probabilidad es $\frac{9}{20}=0.45$.
  • Para el grupo 4 - 6: Hay $1 + 3+ 2 = 6$ valores. La probabilidad es $\frac{6}{20}=0.3$.
  • Para el grupo 7 - 9: Hay $2+1 = 3$ valores. La probabilidad es $\frac{3}{20}=0.15$.
  • Para el grupo 10 - 12: Hay $1+1 = 2$ valores. La probabilidad es $\frac{2}{20}=0.1$.

Answer:

The probabilities in the table should be equal to the total number of data - points in each grouping divided by 20. The probability distribution does represent the data in the list.
