If n is a positive integer, how many 4-tuples of integers from 1 through n can be formed
Chapter 9, Problem 5(choose chapter or problem)
If n is a positive integer, how many 4-tuples of integers from1 through n can be formed in which the elements of the4-tuple are written in increasing order but are not necessarilydistinct? In other words, how many 4-tuplesof integers (i, j, k,m) are there with 1 ? i ? j ? k ? m ? n?Unfortunately, we don't have that question answered yet.
