[Question] I have N samples with each separated by distance meters. Probability of
each samples are P0.....Pn-1. Now I need to find probability that at least K of this occurs. There are N samples each with different probabilities , I need to find out K of them occurs . Each can occur only once.
[Difficulty] If it were equal probability things would have been simpler. Since there
can be many combinations now. Total probability of K event out of N occurring with unequal probability is little tricky. Each can occur only
