Chapter 9, Problem 5E(choose chapter or problem)
If n is a positive integer, how many 4-tuples of integers from 1 through n can be formed in which the elements of the 4-tuple are written in increasing order but are not necessarily distinct? In other words, how many 4-tuples of integers (i, j, k,m) are there with 1 ? i ? j ? k ? m ? n?
