There are two candidates A & B running for an office. Suppose that 60% of the voters in the country support candidate A. We pick an individual randomly. Define random variable X = 1, if the individual support candidate A, and X = 0 if the individual supports candidate B. a) What is the expected value of X. b) Use the sample function to draw three random samples of sizes, 10, 1000 and 1000,000 from this binary variable. Calculate the sample mean in each case and show that as n
