Permuation and probability?

agree with goober on the first one....for the second one, I'm guessing you have 9C(ve) unique choices, but then each unique choice has its rearrangements so that would be another (ve)! for each unique choice, so 9C(ve) * (ve)!....though I could be way off as I'm remembering from a long time ago...
