A group of people were asked if they had run a red light in the last year. 497 responded "yes", and 223 responded "no". Find the probability that if a person is chosen at random, they have run a red light in the last year.

P(Run Red Light) = yes answers / total answers
P(Run Red Light) = 497 / (497 + 223)
P(Run Red Light) = 497 / 720
P(Run Red Light) = 0.6903
