A group of people were asked if they had run a red light in the last year. 218 responded "yes", and 270 responded "no". Find the probability that if a person is chosen at random, they have run a red light in the last year.
Probability can be calculated by: # of desired outcomes / total # of outcomes The total number of people that were surveyed is 270+218= 488 people. 218 have run a red light, our desired outcome. So, the equation gives us 218/488, or approximately 44.67%.
