Jacoby · Answer 1

Total pedestrian deaths = 179

Total number of deaths that involved intoxicated driver = 96 + 40 = 136

Two accidents are randomly selected without replacement, thus;

Probability = desired outcome / total number of outcome

Probability = (136/179) x (135/178) = 0.7597x0.7584 = 0.5761
