There are 4 containers arranged on on a ship's deck labeled 1 through 4. Suppose that container i is placed correctly if it is in the ith spot when counting from the left. E.g., container 2 is placed correctly if it is in the second spot counting from the left. If they are randomly ordered, let X be the number of containers that are correctly placed. a. Find the probability function f(x) of X. (Show your work). Enter the value: f(1) = 1/3

You want to estimate how many fish there are in a small pond. Let's suppose that you first capture n1=500 fish, tag them, and throw them back into the pond. After a couple of days you go back to the pond and capture n2=120 fish, of which k=30 are tagged. Estimate the number of fish in the pond. There are approximately Answer fish in the pond.
