Explanation Calculation: The summarized table of the 985 pedestrian deaths that were caused by accidents is given. The summarized table is given below: Pedestrian intoxicated Pedestrian not intoxicated Total Driver intoxicated 59 79 138 Driver not intoxicated 266 581 847 Total 325 660 985 Here, one pedestrian death is randomly selected from the 985 pedestrian deaths. Probability that the pedestrian was intoxicated: Consider event A = pedestrian was intoxicated. The number of individuals under the event, pedestrian was intoxicated is, n ( A ) = 59 + 266 = 325 . The total sample size is n ( S ) = 59 + 266 + 79 + 581 = 985 . The probability that the pedestrian was intoxicated is, P ( A ) = n ( A ) n ( S ) = 325 985 = 0.3299 Thus, the probability that the pedestrian was intoxicated is 0.3299. Probability that the driver was not intoxicated: Consider event B = driver was not intoxicated. The number of individuals under the event, driver was not intoxicated is, n ( B ) = 266 + 581 = 847 . The total sample size is n ( S ) = 59 + 266 + 79 + 581 = 985 . The probability that the driver was not intoxicated is, P ( B ) = n ( B ) n ( S ) = 847 985 = 0
