how do i find the formula for this problem, i can't even find an example of it in my text book.
A conservationalist wants to find out how many deer are in a preserve. The conservationalist tags 634 deer then releases them. Later, she comes back and catches 342 deer, but 171 of them are already tagged. how many deer are in the preserve?

I have trouble with word problems they are the worst! please help me!!!

1. It's not an exact calculation here that the conservationist is doing, but producing an estimate. What she's discovered is that approximately 50% of the deer in the park (171 out of a sample of 342) have now been tagged. So her original 634 deer ought to be about half the population of the park.

2. It's referred to as the "mark-and-recapture" technique: you can find it under "Mark and Recapture" in Wikipedia, together with examples of the math involved.
