Answer to Question 1

Possible samples:
Daniel-Daniel-Daniel, Daniel-Daniel-Sam, Daniel-Daniel-Carl, Daniel-Sam-Daniel, Daniel-Sam-Sam, Daniel-Sam-Carl, Daniel-Carl-Daniel, Daniel-Carl-Sam, Daniel-Carl-Carl, Sam-Daniel-Daniel, Sam-Daniel-Sam, Sam-Daniel-Carl, Sam-Sam-Daniel, Sam-Sam-Sam, Sam-Sam-Carl, Sam-Carl-Daniel, Sam-Carl-Sam, Sam-Carl-Carl, Carl-Daniel-Daniel, Carl-Daniel-Sam, Carl-Daniel-Carl, Carl-Sam-Daniel, Carl-Sam-Sam, Carl-Sam-Carl, Carl-Carl-Daniel, Carl-Carl-Sam, Carl-Carl-Carl

Proportions: 1, 1, 2/3, 1, 1, 2/3, 2/3, 2/3, 1/3, 1, 1, 2/3, 1, 1, 2/3, 2/3, 2/3, 1/3, 2/3, 2/3, 1/3, 2/3, 2/3, 1/3, 1/3, 1/3, 0

The sampling distribution of proportions consists of the 27 proportions paired with the probability of 1/27.
The mean of the sampling distribution is 2/3
