(a) Count the number of ways to select a sample of 3 people to serve on a board of directors from a population of 6 people. (b) If a simple random sampling procedure is to be employed, the chances that any particular sample will be the one selected are

a) 20

b) Equally likely, 0.05

Step-by-step explanation:

We are given the following in the question:

Population size, n = 6

Sample size, r = 3

a) Ways to select a sample of 3 from a population of 6

Thus, there are 20 ways in which a sample of 3 can be selected from a population of 6.

b) The chances that any particular sample will be the one selected are equally likely.

Probability of selecting one particular sample  =

Thus, 0.05 is the equally likely probability of selecting one sample.
