Answer

Explanation:

Step1: Calcular el número total de personas observadas

$$2 + 6 + 3 + 1 = 12$$

Step2: Determinar la probabilidad experimental de cabello negro

$$P(\text{negro}) = \frac{6}{12} = \frac{1}{2}$$

Step3: Calcular el valor esperado para 16 personas

$$E = 16 \times \frac{1}{2} = 8$$

Answer:

8 black-haired people
