Question 1061664
I'll take a shot at this.
Disregarding the other 7 people, the 3 that want 
to sit together can be seated {{{ 3*2*1 = 6 }}}
different ways.
-------------------
Thinking of these 3 people as a group, they can be 
inserted in a group of 7 others in {{{ 7 }}} ways
--------------------
The group of 7 persons can be seated in 
{{{ 7*6*5*4*3*2*1 }}}different ways
--------------------
I think the answer is
{{{ 7*( 3*2*1 )*( 7*6*5*4*3*2*1 ) }}}
You can do the calculation
