Probability and Statistics of Running Red Lights

The video tutorial explains how to calculate the probability of a person having run a red light in the last year. It starts by identifying the total and favorable outcomes, simplifies the fraction, and then converts it to a decimal and percentage. The tutorial uses a scientific calculator to demonstrate these calculations, providing a clear understanding of probability concepts.
