Answer

Explanation:

Step1: Calcular el total de criaturas

$97 + 47+77=221$

Step2: Calcular la probabilidad de elegir un pollo

$\text{Probabilidad de pollo}=\frac{97}{221}\approx 0.44$

Step3: Calcular la probabilidad de elegir una vaca

$\text{Probabilidad de vaca}=\frac{47}{221}\approx 0.21$

Step4: Calcular la probabilidad de elegir un humano

$\text{Probabilidad de humano}=\frac{77}{221}\approx 0.35$

Answer:

Chicken: $\frac{97}{221}\approx 0.44$ Cow: $\frac{47}{221}\approx 0.21$ Human: $\frac{77}{221}\approx 0.35$
