Question

Suppose that 52% of all voters prefer the Democratic candidate. Let X be the number of people who prefer the candidate when 43 people are surveyed at random. When choosing a type of distribution, select B for Binomial, U for Uniform or N for normal. What is the distribution of X? X ~ B( , ) Please show the following answers to 4 decimal places. What is the probability that exactly 13 voters who prefer the Democratic candidate in the survey? What is the probability that less than 13 voters who prefer the Democratic candidate in the survey? What is the probability that at most 13 voters who prefer the Democratic candidate in the survey? What is the probability that between 12 and 23 (including 12 and 23) voters who prefer the Democratic candidate in the survey?
