In the 1984 U.S. presidential election, approximately 60% voted Republican and 40% voted Democratic. Calculate the probability that a random sample would correctly forecast the election winner - that is, that a majority of the sample would be Republicans, if the sample size were: (a) n = 1 (b) n = 3 (c) n = 9 (d) Comment on the probability of a correct forecast changes as the sample size increases.
