What about cows? Well, 47 of the 221 are cows. So there's a 47, two 21st probability of getting a cow. And then, last but not least, you have 77 of the 221s are human. Is this a legitimate probability distribution? Well, add these up. If you add these three fractions up, the denominator's gonna be 221, and we already know that 97 plus 47 plus 77 is 221, so it definitely adds up to one, and none of these are negative.
