i need help evaluating this sum:
(that is 100 P i, or the permutation)
What does "100 P i" mean with i going from 1 to 100? Is P a constant?
I can't see your attatchment. Does 100 P i mean the number of permuations of i objects selected from 100? namely, 100 P i= 100!/(100-i)!
What's being summed?
yeah i'm sorry if it came out bad, but yeah it's the permutation
So what's being summed then?
I'm going to take a stab in the dark and guess you mean
Am I close?
yeap, that's exactly it. is there any explicit way to calculate the sum for arbitrary n?
Separate names with a comma.
