welcome to pf!

hi godsaveme! welcome to pf!

there are two birds in a tree, and a hunter shoots one

how many birds are there now in the tree, and are they dead or alive?​

this is a common-sense question, not a maths question! …

what do you think the answer is?

To me, it sounds like he is trying to articulate this trick question I've heard here and there in the past.

The question comes in various forms but basically is, 20 birds are in a tree. A hunter shoots one, how many are left?

The answer is that only one is left, the dead one. The others have flown off at the sound of the gun shot.

That depends on what the word "shot" means in the original question.

You didn't say what the hunter shot. "The hunter shot one." One what? One giraffe? There are two birds in the tree as per your definition.

Re: welcome to pf!

you can say,there are 0,1,2 birds in the tree
but when there is one bird in the tree ,you can not sure it is dead or alive.

you get three answers of this question,
but we get four answers,that means You have been misled by the figures

You have a 50% probability of guessing right
If you're lucky,you will be right.Otherwise, you're wrong.
