Bear population. To estimate the size of the bear

population on the Keweenaw Peninsula, conservationists

captured, tagged, and released 50 bears. One year later, a

random sample of 100 bears included only 2 tagged bears.

What is the conservationist’s estimate of the size of the

bear population?

Solution:

Population: x

x/100 = 50/2

x = 2500

So the bear population is 2500
