Answer

Explanation:

Step1: Calcular la probabilidad de elegir un mármol naranja

Hay 3 mármoles en total y 1 es naranja. La probabilidad $P$ de elegir un mármol naranja en un solo intento es $P=\frac{1}{3}$.

Step2: Calcular la predicción para 6 intentos

Multiplicamos la probabilidad por el número de intentos. Sea $n$ el número de veces que se espera elegir un mármol naranja. Entonces $n = \frac{1}{3}\times6$. $n = 2$.
