I'm confused.
Shouldn't the middle one be 1:5 instead of 5:1?
And then the last one should be 7:15 right?

Isn't it 100% chance that the trapped animal will be a fox?

If the marks on the chicken coups are only from foxes, wouldn't you a trap set up near the coup wouldn't catch more foxes than raccoons despite the ratio of the populations.

Likelihood ratio is backwards. With the new likelyhood ratio (17% raccoon 83% fox), we get 32% coon 68% fox

>caring if a coon gets hurt
Honestly, who wrote this question? When it comes to nuisance animals, the average farmer has no qualms about industrializing mass-murder.

>I want to trap the animal, but I only have traps for foxes. If a raccoon goes in, it will get hurt.

Why is this information needed?

65% Fox
32% Racoon

I just got it by:
Fox pop x 5 (Since they are five times more likely to enter coop)
New pop ratio 15:7 (Fox:Raccon)
or 65% Fox, 32% Racoon.

Maybe its weird multiplying the fox pop, but I think it makes sense.

>if a racoon goes in it, it will get hurt
So essentially:
>if a fox goes in, the trap catches the fox
>if a racoon goes in, the trap hurts the racoon
So the probability of the animal caught being a fox is 100%, since the trap doesn't catch racoons.
Either that or the person who wrote the question is retarded.
