Answer

Answer:

50

Explanation:

Step1: Analizar la tendencia

Observando los datos, vemos que la proporción de caras se aproxima a la mitad conforme aumenta el número de lanzamientos.

Step2: Inferir para 100 lanzamientos

Para 100 lanzamientos, en una moneda justa, esperaríamos 50 caras. Y siguiendo la tendencia de los datos, se aproxima a este valor.
