man yum.conf look for group_package_types:
        group_package_types
        List  of  the following: optional, default, mandatory. Tells yum
        which  type  of  packages  in  groups  will  be  installed  when
       ’groupinstall’ is called.  Default is: default, mandatory

Run echo 'n' | yum groupinstall groupname
that'll show you. However, which pkgs will be installed will be dependent 
on which pkgs are already installed.
