Solution Steps

Step 1: Identify the Specific Outcome of Interest

The specific outcome of interest is: [('No', 'Yes'), ('Yes', 'No'), ('Yes', 'Yes')].

Step 2: Calculate the Relevant Frequencies

The relevant frequencies for the outcome of interest are: 231.

Step 3: Calculate the Total Number of Observations

The total number of observations (N) is: 981.

Step 4: Compute the Probability

The probability of the outcome of interest is calculated as $P = \frac{231}{981}$.

34% of likely U.S. voters think that the federal government should get more involved in fighting local crime. You randomly select six likely U.S. voters and ask them whether they think that the federal government should get more involved in fighting local crime. The random variable represents the number of likely U.S. voters who think that the federal government should get more involved in fighting local crime. Find the mean of the binomial distribution. μ=2.0 (Round to the nearest tenth as needed.) Find the variance of the binomial distribution. σ^2= (Round to the nearest tenth as needed.)
