A group of people were asked if they had run a red light in the last year. 451 responded "yes," and 129 responded "no." What is the probability of randomly selecting a person who has run a red light based on this data?

Final answer:

The probability of randomly selecting a person who has run a red light from the group is approximately 77.76%, calculated by dividing the number of 'yes' responses (451) by the total number of responses (580).

Step-by-step explanation:

To calculate the probability of randomly selecting a person who has run a red light, we use the experimental probability formula which is the ratio of the number of favorable outcomes to the total number of outcomes. In this case, the number of people who responded "yes" to running a red light is 451, and the total number of respondents is the sum of those who responded "yes" and "no", which is 451 + 129. Therefore, the probability is calculated as follows:

Probability = Number of people who ran a red light / Total number of respondents

Probability = 451 / (451 + 129)

Probability = 451 / 580

Probability ≈ 0.7776 or 77.76%

The experimental probability that a randomly selected person from this group has run a red light is approximately 77.76%.
