Answer to Question #301520 in Statistics and Probability for Mechelle Hamili

Question

How many samples of size n=3 can be drawn from this population?

Answer 1

The population size is $N=12$. The number of possible samples of size $n=3$  that can be drawn from this population without replacement is $\binom{N}{n}=\binom{12}{3}=220$  

The number of samples that can be drawn from this population with replacement is $N^n=12^3=1728$
