Using group by of two columns and count in sql

Here is explanation of Using group by of two columns and count in sql as below, lets say we have two table Emp and Dep.

Select * from [dbo].[tblDep]

id	name
1	IT
2	HR
3	Finance

Select * from [dbo].[tblEmp]

Empid	name	Gender	depId
1002	Jatin	male	1
1003	Nirmal	male	1
1004	Aditi	Female	1
1005	Abhi	male	2
1006	nisha	female	2
1007	dipti	female	2

so here we want group of male and female employee per department with count.

SELECT a, b, COUNT(a) FROM tbl GROUP BY a, b 
So query would be like,

here a = department Name, b = Gender

Select d.name, e.Gender, count(d.name)
from [dbo].[tblDep] d inner join [dbo].[tblEmp] e
on d.id = e.depId
group by d.name, e.Gender
order by d.name, e.Gender
