"In a population of v = u + d voters, u are undecided but the remaining d voters have decided how they will vote. If a simple random sample of 20 voters is taken, what is the chance that there are at least 5 undecided voters and at least 10 who have decided? You can assume that both It and d are greater than 20." The student shows the GSI the following answer and asks if it is right. 3:5 (2) (ZOdk) . $210 (if) (201:!) (2%) (2'3) 0 If the answer is right, explain the reasoning in detail, including all uses of distributions and the rules of probability. - If the answer is wrong, provide the right answer.
