A population consists of only four individuals identified as A, B, C, and D. Your job is to select a simple random sample of two individuals from this population.

a. Assuming that you are using sampling without replacement, list all of the possible random samples that could be obtained. (Hint 1: List the samples systematically; for example, begin with all of the samples with individual A as the first person selected. Hint 2: If the same people are selected in two different orders, it counts as two different samples. For example, if A is selected first, then B, it is a different sample than if B were selected first, then A. Hint 3: You should obtain 12 different samples.)

b. Assuming that you are using sampling with replacement, list all of the possible random samples that could be obtained. Note: The same hints apply as in part a, except that you should now obtain 16 different samples.
