Answer

Explanation:

Step1: Contar casos favorables

Contamos los casos en el espacio muestral donde al menos 2 monedas caen cara (H). Son HHH, HHT, HTH, THH, es decir 4 casos.

Step2: Calcular probabilidad teórica

El espacio muestral tiene 8 casos en total. La probabilidad $P$ de que al menos 2 monedas caigan cara es $P=\frac{4}{8}=\frac{1}{2}$.

Step3: Predecir repeticiones

Si repetimos el experimento 240 veces, el número de repeticiones esperadas con al menos 2 monedas cara es $240\times\frac{1}{2}$. $240\times\frac{1}{2}=120$

Answer:

120
