Just some very incidental comments here.
Dennis's reply is a valid approach.
If however the integers represent records, in which the apparent number is
like the number on a football jersey, then the problem is somewhat
different. The problem here becomes selection of an unbiased choice of n
records at random from a file containing N records. Here n=1 and N= 9
(1,2,3,4,5,6,7,8,9). Knuth (The Art of Computer Programming, Vol 2) on page
142-143 discusses this problem and gives an algorithm for its solution.
