This video is all about Capture Recapture and forms part of the playlist with the same name. I've also added to the playlist on GCSE higher revision.

Ravina wants to find an estimate for the number of eagles in a sanctuary. She catches a sample of 70 and tags each of them. The birds are then released.
The next day she catches a sample of 60 eagles. 12 of these eagles are tagged.
Work out an estimate for the total number of eagles in the sanctuary.
