Find the number of ways of seating 10 people around a table if three people are to sit together.
The answer is 4320, but i got 30240.
I did:
Let the 3 people be one group. Therefore, there are 8 groups.
Total arrangements of groups x arranging the 3 people in the one group
(8-1)! x 3! = 30240.
Thanks very much![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
