The following data summarizes results from 908 pedestrian deaths that were caused by accidents. If one of the pedestrian deaths is randomly selected, find the probability that the pedestriand was intoxicated or the driver was intoxicated.
Pedestrian
Intoxicated Not intoxicated
Driver Intoxicated 68 68
Not Intoxicated 222 550
P(pedestrian was intoxicated or driver was intoxicated) =
(round to three decimal places as needed)
Solution
P(pedestrian was intoxicated or dirver was intoxicated) = (sum of elements in union of either being toxicated)/Total = (68+68+222)/550 = 0.651
