Para determinar la calificación más probable, debemos identificar la calificación que aparece con más frecuencia en la lista. Al revisar los datos, podemos contar las veces que aparece cada calificación:
  • 6 aparece 1 vez,
  • 7 aparece 4 veces,
  • 8 aparece 6 veces,
  • 9 aparece 7 veces,
  • 10 aparece 5 veces.
La calificación que más veces se repite es la 9, con 7 apariciones. Por lo tanto, la respuesta correcta es (D) 9.
¡Así que la próxima vez que elijas un estudiante al azar, es muy probable que tenga una calificación de 9! ¿No es curioso cómo los números van contando sus propias historias?
