When relating to the equation, we need to convert a fraction into a percentage. When relating to 6 of 20 people getting a red light, the fraction is: 6/20.
When converting to percentage, divide the numerator by denominator, and multiply by 100.
6 divided by 20 is 0.3.
0.3 multiplied by 100 is 30.
Therefore, there is a 30% chance of people getting a red light.
