<br>
The group can have either 6 sophomores, or 5 sophomores and 1 freshman:<br>
{{{C(9,6) + (C(9,5)*C(6,1))}}}<br>
You could be more mathematically "complete" by saying the group can have either 6 sophomores AND 0 FRESHMEN, or 5 sophomores and 1 freshman:<br>
{{{(C(9,6)*C(6,0)) + (C(9,5)*C(6,1))}}}<br>
Use a calculator if necessary to get a numerical answer.<br>
