Case analysis (state all calculations and analysis processes required for analysis)

Example 5. You run a private company and employ nine employees. The abilities, responsibilities and scope of work of the nine employees are all the same (all nine employees have the same conditions). The probability of all employees making mistakes is the same. The records of employees making mistakes over the past year are as follows. The content and importance (severeness) of all mistakes are the same.

Staff evaluation is done at the end of the year. Consider how you can determine the employee's reward and punishment based on the number of mistakes made in the past year (you may write answers without mathematical calculations).
