I've been trying to figure out something that should be simple but I seem 
to be stuck. Perhaps someone can help. I need to figure out what the 
probability of NOT finding a fragment which is r bp long in a sequence 
which is n bp long. I can do this for individual cases but I need a 
purely symbolic solution which would cover all cases. This is all 
assuming a completely random sequence. 
If anyone happens to know off the top of their heads what the solution is 
it would be grotesquely appreciated.
Thanks,

Adlai Burman
