The probability that a person chosen at random favors the legislation is calculated by dividing the total number of people who favor the legislation by the total number of people surveyed. According to the table, 176 people favor the legislation out of a total of 263 people surveyed. Therefore, the probability is $ \frac{176}{263} $, which is approximately 0.67.
