1. Urula is doing a project and has caughed, tagged and released 50 possums. Estimate the population of the possums in the park. Three nights later she captures a sample. 2. If ursula captures 20 possums and 4 of them are tagged, what would her estimate of the local possum population be? 3. 4/20 = 0.2 0.2 x 100 = 20% 50 x (100/20) = 250 Just want to know on reassurance, Im not sure were to start here!
