You're taking samples of size 10 from a population of 20 marbles and recording the number of blue marbles in each sample. Why isn't this a binomial situation, and why would it be almost binomial if you did the same experiment with a population of 200 marbles?

Answer:

p is not constant

Step-by-step explanation:

The sample is picked without replacement so p is not constant.

With a population of 200, p would be approximately same for all 10.

When the population is large, you can assume p is constant even if without replacement
