Problem #201
Tricky Game
TNBT likes playing with sticks, so once he broke a stick into 3 pieces and calculated the probability of the pieces forming a triangle with much difficulty. He now wishes to calculate the probability of the pieces NOT forming an N-sided polygon given the stick was broken into N pieces. Since he found it difficult for 3 pieces, tell him the answer for N = 733.
If the probability is p/q where gcd(p, q)=1, the answer is [q/p] modulo 10^9+9.
[x] represents the greatest integer \leq x.
