To find the expected number of correct answers in a survey of 500 people, we first determine the proportion of correct answers from the initial survey: 25 out of 150, which is ( \frac{25}{150} = \frac{1}{6} ) or approximately 0.167. Applying this proportion to the new survey size of 500, we calculate ( 500 \times \frac{1}{6} ), which equals approximately 83.33. Therefore, we can expect around 83 people to answer the question correctly in the larger survey.
