Best answer 4 votes 4 votes Answer should be 8C4x((4 - 1)!)^2 = 2520. All possible ways of making two groups of 4 people out of 8 people = 8C4. IN EACH ROUND TABLE, all possible ways of arranging 4 people = (4 - 1)! Which gives 8C4x((4 - 1)!)^2 = 2520. अनुराग पाण्डेय answered Sep 27, 2015 अनुराग पाण्डेय 1.4k points comment Share See all 0 reply Please log in or register to add a comment.
