Hello!  Can you tell me which role code has the largest number of employees associated with it?
select role_code from employees group by role_code order by count ( * ) desc limit 1
Great!  Can you tell me how many employees have ED as their Role_code?
select count ( * ) from employees where role_code = "ED"
Excellent!  Would you be able to provide me with a list of the names and genders of those 7 employees?
select employee_name,gender_mfu from employees where role_code = "ED"
