sharathn Posted December 29, 2008 Share Posted December 29, 2008 Hi, 8 Men and 2 Women can be seated around the table in (10-1)! ways. No of ways you can arrange 2 women around a table sitting opposite to each other = 10 No of ways we can arrange 8 men = 8! totoal no of ways you can arrange 8 men and 2 women where the 2 women sitting opposite to each other = 10 * 8! total no of ways you can arrange 8 men and 2 women around a table, where the 2 women are not sitting opposite to each other = 9! - 10 * 8! Thanks, Sharath Quote Link to comment Share on other sites More sharing options...
