Step1: Calculate total number of people
The total number of people is the sum of those who responded "yes" and those who responded "no". So, $205 + 424=629$.
Step2: Calculate the probability
The probability $P$ that a randomly - chosen person has run a red light is the number of people who responded "yes" divided by the total number of people. So, $P=\frac{205}{629}\approx0.326$.
