Answer

Explanation:

Step1: Identificar casos favorables

Contamos los casos donde al menos 2 monedas caen en tails. Son HTT, THT, TTH, TTT, es decir 4 casos.

Step2: Calcular la probabilidad

La probabilidad $P$ se calcula como el número de casos favorables $n_f$ dividido por el número de casos totales $n_t$. Aquí $n_f = 4$ y $n_t=8$. Entonces $P=\frac{4}{8}=0.5$.

Answer:

50%
