WAIT I HAVE A WAY
@hba having epiphanies are we?
IF UR ASKED OF A ROW THEN n! IF UR ASKED ABOUT A CIRCLE OR ROUND ITS (n-1)! AND IF ITS A NECKLACE OR GARLAND ITS 1/2(n-1)!
IN UR CASE IT WOULD BE (8-1)! =7!
AND 2 TABLES SO U MULTIPLY IT BY 2 THEN
Remember that a circular permutation is (n – 1)!
Break the seating process into "activities" like this:
1) Choose the people who are seated at each table. C(8,4 = 8•7•6•5/4•3•2•1 = 70). When you choose for 1 table the other four automatically go to the other table.
2) Arrange the 4 people at table A: (4 – 1)! = 3! = 6
3) Arrange the 4 people at table B. Also 3! =6
So answer is C(8,4)•3!•3! = 70•6•6 = 2520
he copied it from somewhere :D
anyway ... nice work @hba :D
