Among the employees, give me the full names of those who have less than 4 territories.
less than 4 territories refers to EmployeeID where Count(TerritoryID) < 4
SELECT T1.FirstName, T1.LastName FROM Employees AS T1 INNER JOIN EmployeeTerritories AS T2 ON T1.EmployeeID = T2.EmployeeID WHERE T2.EmployeeID < 4
