Answer

Explanation:

Step1: Calcular el total de canciones

Sumamos todos los valores de la tabla: $7 + 5+5 + 3=20$.

Step2: Encontrar el número de canciones que cumplen las condiciones

El número de canciones que son rock y tuvieron 501 - 1000 plays es 3.

Step3: Calcular la probabilidad

La probabilidad $P$ se calcula como el número de casos favorables dividido por el número total de casos. Entonces $P=\frac{3}{20}$.

Answer:

$\frac{3}{20}$
