Step 1 :We are given a problem involving exit polling, where we have a sample of 400 voters, 204 of whom voted for a certain referendum. We are asked to find the likelihood of this result if the population proportion of voters in favor of the referendum is 0.49.
Step 2 :This is a problem of binomial distribution, where we have a number of trials (n=400), a number of successes (x=204), and a probability of success (p=0.49).
Step 3 :We need to find the probability of getting more than 204 successes. This is equivalent to finding the probability of getting 204 or fewer successes and subtracting that from 1.
Step 4 :Using the cumulative distribution function (CDF) for a binomial distribution, we find that the probability of getting 204 or fewer successes is approximately 0.8024.
Step 5 :Subtracting this from 1, we find that the probability of getting more than 204 successes is approximately 0.1976.
Step 6 :Thus, the final answer is \(\boxed{0.1976}\), which represents the probability that more than 204 people voted for the referendum.
