Factory workers are constantly encouraged to practice zero tolerance when it comes to accidents in factories. Accidents can occur because the working environment or conditions themselves are unsafe. On the other hand, accidents can occur due to carelessness or so-called human error. In addition, the worker's shift, 7:00 A.M. to 3:00 P.M. (day shift), 3:00 P.M. to 11:00 P.M. (evening shift), or 11:00 P.M. to 7:00 A.M. (graveyard shift), may be a factor. During the last year, 500 accidents have occurred. The percentages of the accidents for the condition combinations are shown in the accompanying table. Complete parts (a) through (d) below. 1 Click the icon to view the data on accidents. (a) If an accident report is selected randomly from the 500 reports, what is the probability that the accident occurred on the evening shift? (Type an integer or a decimal. Do not round.) (b) If an accident report is selected randomly from the 500 reports, what is the probability that the accident occurred due to human error? (Type an integer or a decimal. Do not round.) (c) If an accident report is selected randomly from the 500 reports, what is the probability that the accident occurred due to unsafe conditions? (Type an integer or a decimal. Do not round.) (d) If an accident report is selected randomly from the 500 reports, what is the probability that the accident occurred on either the evening or the graveyard shift?
