A certain manufacturing company encourages it's employees to practice zero tolerance when it comes to workplace accidents. 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 employee's shift, 7:00 A.M.–3:00 P.M. (day shift), 3:00 P.M.–11:00 P.M. (evening shift), or 11:00 P.M.–7:00 A.M. (graveyard shift), may be a factor. During the last year, 300 accidents have occurred. The percentages of the accidents for the condition combinations are as follows: Unsafe Conditions Human Shift Error Day Evening Graveyard 5% 6% 2% 32% 25% 30% If an accident report is selected randomly from the 300 reports; what is the probability that the accident occurred due to human error? What is the probability that the accident occurred on either the evening of the graveyard shift? (Show complete solution in your answer sheet) D a. None among the choices O b.32%, 63% O c. 96 and 189 accidents O d. 68%, 37%
