Question

Eighty five fish are tagged and released into a pond. A later sample of 94 fish from the pond contains 13 tagged fish. Estimate the number of fish in the pond

Answer 1

Hi Luke,

 

we can set up a proportion to solve this

 

13/85 = 94/x

 

we can cross mutilply and solve for x

 

13x = 85*94

 

x = 614.61

 

Estimate is 615 fish in the pond

 

Hope this helps
