    Assuming the table is at employee id level;
    SELECT sex, count(*) as emp_count
    FROM Employees
    WHERE DOB BETWEEN ’01-01-1960′ AND ’31-12-1975′
    GROUP BY sex

    /*When you use the BETWEEN operator with date values, to get the best result, you should use the type cast to explicitly convert the type of column or expression to the DATE type*/

    Select count(*) as Number_of_Employees
    from Employees
    where DOB BETWEEN CAST(‘1960-01-01’ as DATE) and CAST(‘1975-12-31’ as DATE)
    Group by Sex;
