Vedclass · Answer

(D) First,arrange the $8$ men around a circular table. The number of ways to arrange $n$ objects in a circle is $(n-1)!$. So,the number of ways to arrange $8$ men is $(8-1)! = 7!$. After arranging the men,there are $8$ gaps created between them. To ensure no two women sit together,we must place the $4$ women in these $8$ gaps. The number of ways to choose and arrange $4$ women in $8$ gaps is given by the permutation formula ${}^{8}P_{4}$. Therefore,the total number of ways is $7! 	imes {}^{8}P_{4}$.
