In designing an experiment involving a treatment applied to 5 test subjects, , researchers plan to use a simple random sample of 5 subjects selected from a pool of 59 available a subjects. ( recall that with a simple random sample, all sample of the same size have the same chance of being selected answer question below. How many different simple random samples are possible? And what is the probability of each simple random sample in this case?

Solution
C( 59,5 ) = 5006368 different random samples are possible.
Probability = C(5,5) / C (59,5 ) = 1.99746E-07
