The Organizational Development Journal (Summer 2006) reported on the results of a survey of human resource officers (HROs) at major firms. The focus of the study was employee behavior, namely absenteeism, promptness to work, and turnover. The study found that 55% of the HROs had problems with absenteeism. Also, 41% of the HROs had problems with turnover. Suppose that 22% of the HROs had problems with both absenteeism and turnover.
a. Find the probability that a human resource officer selected from the group surveyed had problems with employee absenteeism or employee turnover.
b. Find the probability that a human resource officer selected from the group surveyed did not have problems with employee absenteeism.
c. Find the probability that a human resource officer selected from the group surveyed did not have problems with employee absenteeism nor with employee turnover.
