Answer:

Following are the solution to this question:

Step-by-step explanation:

They provide various boxes or various objects. It also wants objects to be distributed into containers, so no container is empty. All we select k objects of r to keep no boxes empty, which (r C k) could be done. All such k artifacts can be placed in k containers, each of them in k! Forms. There will be remaining $(r-k)$ objects. All can be put in any of k boxes. Therefore, these $(r-k)$ objects could in the $k^{(r-k)}$ manner are organized. Consequently, both possible ways to do this are

$=\binom{r}{k} \times k! \times k^{r-k}\\\\=\frac{r! \times k^{r-k}}{(r-k)!}$

Consequently, the number of ways that r objects in k different boxes can be arranged to make no book empty is every possible one

$= \frac{r!k^{r-k}}{(r-k)!}$
