Vedclass · Answer

(D) The number of ways to arrange $n$ distinct objects in a circle is $(n - 1)!$. For a garland (or necklace),the clockwise and counter-clockwise arrangements are considered identical because the garland can be flipped over. Therefore,the number of ways to make a garland from $n$ flowers is $\frac{(n - 1)!}{2}$. Given $n = 10$,the number of ways is $\frac{(10 - 1)!}{2} = \frac{9!}{2}$.

In how many ways can a garland be made from exactly $10$ flowers?
