Answer

Explanation:

Step1: Calcular el total de estudiantes

Sumamos todos los valores de la tabla: $3 + 4+6 + 14=27$.

Step2: Identificar el número de estudiantes que cumplen la condición

Los estudiantes que durmieron 6 horas o menos y no tienen un A son 14.

Step3: Calcular la probabilidad

La probabilidad $P$ se calcula como el número de casos favorables dividido por el número total de casos. Entonces $P=\frac{14}{27}$.

Answer:

$\frac{14}{27}$
