Assuming that the 26 letters in the English language alphabet comprise a population,

1.Briefly explain how a simple random sample of size n = 6 can be determined to contain unique letters.

2.Showing your work, find the total number of simple random samples of size n = 6 possible (each sample containing unique letters).

3.What is the probability of drawing a simple random sample of size n = 6 containing C, D, G, P, Q, and Z at first attempt, from a bag containing 26 ping pong balls, each uniquely labeled one of the 26 letters?
