Final answer:
To calculate the proportion of employees who either have MBAs or are managers, add the proportion of employees who have MBAs to the proportion of employees who are managers, and subtract the proportion of employees who are both managers and have MBAs. In this case, the proportion of employees who either have MBAs or are managers is 26%.
Step-by-step explanation:
To calculate the proportion of employees who either have MBAs or are managers, we need to add the proportion of employees who have MBAs to the proportion of employees who are managers and then subtract the proportion of employees who are both managers and have MBAs (to avoid double counting).
The proportion of employees who have MBAs is 34%, and the proportion of employees who are managers is 25%. The proportion of managers who have MBAs is 33%.
Using this information:
Proportion of employees who have MBAs or are managers = (Proportion of employees with MBAs) + (Proportion of employees who are managers) - (Proportion of employees who are both managers and have MBAs)
= 34% + 25% - 33%
= 59% - 33%
= 26%
