Answer

Explanation:

Step1: Calcular el total de lanzamientos

Sumamos las frecuencias de todas las letras: $6 + 8+7 + 9=30$.

Step2: Calcular la probabilidad experimental de B

La probabilidad experimental de que salga B es la frecuencia de B dividida por el total de lanzamientos. Entonces, $\frac{8}{30}=\frac{4}{15}$.

Answer:

$\frac{4}{15}$
