Explanation:

Step1: Calculate total number of people

Total number of people = Number of "yes" + Number of "no"
$460 + 443=903$

Step2: Calculate probability

Probability formula: $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$
Here, number of favorable outcomes (people who ran red - light) is $460$, total number of outcomes is $903$
$P=\frac{460}{903}\approx0.509$

Answer:

$0.509$
