Answer

Explanation:

Step1: Calcular el total de participantes

Sumamos todos los valores de la tabla: $4 + 4+3 + 4=15$.

Step2: Encontrar el número de participantes de Canadá con puntuación hasta 100 puntos

De la tabla, vemos que 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 $P=\frac{3}{15}=\frac{1}{5}$.

Answer:

$\frac{1}{5}$
