Question 479413: 45. A national pollster has developed 15 questions designed to rate the performance of the
president of the United States. The pollster will select 10 of these questions. How many
different arrangements are there for the order of the 10 selected questions?

Since arrangements are required this is a permutation.
nPr=15P10=15!/(15-10)!
=15!/5!
=10897286400 arrangements
