High in the rocky mountains, a biology research team has drained a lake to get rid of all fish. After the lake was refilled, they stocked it with an endangered species of Greenback trout. Of the 2000 greenback trout put into the lake 800 were tagged for later study. An electrshock method is used on indiviual fish to get a study sample. However, this method is hard on the fish. The research team wants to know the smallest number of fish that must be electroshocked to be at least 90% sure of getting a sample of two or more tagged trout. Please provide the answer.

Answer n=800 fish

Step-by-step explanation:

High in the Rocky Mountains, a biology research team has drained a lake to get rid of all fish. After the lake was refilled, they stocked it with an endangered species of Greenback trout. Of the 2000 Greenback trout put into the lake 400 were tagged for later study. An electroshock method is used on individual fish to get a study sample. However, this method is hard on the fish. The research team wants to know the smallest number of fish that must be electroshocked to be at least 50% sure of getting a sample of two or more tagged trout.

we have to find out smallest number fish (n) that must be electroshoked to be atleast 50% &

species of Greenback trout of the 2000 greenback trout put into the lake 400

correct answer:

a + bi

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
