Each year CCH, Inc., a firm that provides human resources and employment law information, conducts a survey on absenteeism in the workplace. The latest CCH Unscheduled Absence Survey found that of all unscheduled work absences, 34% are due to "personal illness," 22% for "family issues," 18% for "personal needs," 13% for "entitlement mentality," and 13% due to "stress." Consider a randomly selected employee who has an unscheduled work absence.
a. List the sample points for this experiment.
b. Assign reasonable probabilities to the sample points.
c. What is the probability that the absence is due to something other than "personal illness"?
