You are a space alien. You visit planet Earth and abduct 979797 chickens, 474747 cows, and 777777 humans. Then, you randomly select one Earth creature from your sample to experiment on. Each creature has an equal probability of getting selected. Create a probability model to show how likely you are to select each type of Earth creature. Input your answers as fractions or as decimals rounded to the nearest hundredth.

97+47+77 = 221

$$P(chicken)=\frac{97}{221}\\ P(cow)=\frac{47}{221}\\ P(human)=\frac{77}{221}\\$$

I don't know what probability model you want but theyare your answers.
