Vedclass · Answer

(B) For each of the $n$ distinct books,there are $p$ copies available. For a specific book,we can choose $0, 1, 2, \dots, p$ copies. This gives $(p + 1)$ choices for each book. Since there are $n$ such books,the total number of ways to select any number of books (including selecting zero books) is $(p + 1)^n$. To select one or more books,we must exclude the case where zero books are selected from all $n$ types. Therefore,the required number of ways is $(p + 1)^n - 1$.

In a library,there are $n$ distinct books and each has $p$ copies. What is the number of ways to select one or more books?
