- Homework Statement
- Wyatt wants to work out an estimate for the total number of wild ponies in a forest

In July, Wyatt catches 42 ponies in the forest

He puts a tag on each of these ponies and releases them

In August, Wyatt catches 60 ponies in the forest

He finds that 5 of the 60 ponies are tagged

Work out an estimate for the total number of ponies in the forest

- Relevant Equations
- N/A

My question; Which branch of maths is this?

Also, can you give me a clue as to where to start regards solving this. Just a hint please, not a full explanation.

I'm struggling to even guess at this one. I did think, '60 ponies, 5 of which are tagged, so, 5/60 tagged, which is 1/12

1/12 of the 60 are tagged...

How does this relate to the initial number of 42 caught, and tagged, then released..?

Of the intial 42 caught, 100% were tagged...

Why did he only catch 42 in July, but caught 60 in August?

If only 5 of the 60 ponies were tagged that means 55 weren't. If 55 weren't, then none of those 55 belong to the first lot of 42 that were caught and tagged. So there is AT LEAST 97 ponies in the forest (?).

Q. They've asked for an estimate for the total number of ponies in the forest; do they want us to include any the 60 that Wyatt has caught at the time of asking, and hasn't released yet?
