A group of people were asked if they had run a red light in the last year. 433 responded "yes", and 424 responded "no".

Find the probability that if a person is chosen at random, they have run a red light in the last year.

433/(433+424)

Actually, that is just the probability that they answered "yes." They may have been lying...

To find the probability that a person chosen at random has run a red light in the last year, we need to divide the number of people who responded "yes" by the total number of people surveyed.

The total number of people surveyed is the sum of those who responded "yes" and those who responded "no":

Total number of people surveyed = 433 + 424 = 857

The number of people who responded "yes" is 433.

Therefore, the probability is:

Probability = Number of people who responded "yes" / Total number of people surveyed

Probability = 433 / 857 ≈ 0.505

Hence, the probability that a person chosen at random has run a red light in the last year is approximately 0.505 or 50.5%.

To find the probability that a person chosen at random has run a red light in the last year, we need to divide the number of people who responded "yes" by the total number of people in the group.

In this case, 433 people responded "yes" and 424 people responded "no". Therefore, the total number of people in the group is 433 + 424 = 857.

So, the probability that a person chosen at random has run a red light in the last year is 433 / 857 ≈ 0.506, or approximately 50.6%.
