Answer

Explanation:

Step1: Calcular el total de banjos

Sumamos todas las frecuencias: $(2 + 5+5 + 2)=14$.

Step2: Encontrar el número de banjos con 4 cuerdas y 25% de descuento

El número de banjos con 4 cuerdas y 25% de descuento es 2.

Step3: Calcular la probabilidad

La probabilidad $P$ se calcula como el número de casos favorables dividido por el número total de casos. Entonces $P=\frac{2}{14}=\frac{1}{7}$.

Answer:

$\frac{1}{7}$
