You can put this solution on YOUR website! For the faculty members:
C( 11, 4 )
For the students:
C( 15, 5 )
-----------------
Each of the groups of 4 faculty members
are able to combine with a group of
5 student members in the following way:
C( 11,4 ) x C( 15, 5 )
---------------------------
C( 11, 4 ) = 
C( 11, 4 ) = 
C( 11,4 ) = 
C( 11,4 ) = 
C( 11,4 ) = 
and
C( 15,5 ) = 
C( 15,5 ) = 
C( 15,5 ) = 
C( 15,5 ) = 
C( 15,5 ) = 
-------------------------------
C( 11,4 ) x C( 15, 5 ) = 
C( 11,4 ) x C( 15, 5 ) = 
------------------------------------
There are 990,990 ways to form a committee
Definitely get a 2nd opinion ( if needed ) on this.
