6 guys (let's call them ABCDEF) sit around a circular table. If the AB must always sit together, and C must face the door, how many arrangements are possible? please explain your work... _________________

1. "C must face the door" - the condition fixes circular shifts. 2. "the AB must always sit together" - we can consider AB one object, but count it twice as AB and BA . 3. We have 4 objects (3 guys and one couple ): 4P4=4!=24 4. finally, N=24*2=48 _________________
