394/679

Step-by-step explanation:

Probability is the measure of likelihood or chance that an event will occur.

Probability = Possible outcome of event/Total outcome

Total number of people asked if they had run a red light = number of people that responded 'yes' + number of people that responded 'no'

Total outcome = 394+285

Total outcome = 679

Possible outcome = number of people that responded yes = 394

Probability that if a person is chosen at chosen at random, they have run a red light in the last year will be 394/679
