Explicación:
Paso 1: Identificar casos favorables
El número de bolas amarillas es 1.
Paso 2: Identificar casos totales
El número total de bolas es 10.
Paso 3: Aplicar fórmula de probabilidad
La probabilidad $P$ se calcula como $P=\frac{\text{casos favorables}}{\text{casos totales}}=\frac{1}{10}$.
Respuesta:
$\frac{1}{10}$
