More PWI Math Problems (Twilight Temple)

Guess it would be fun to do some math related to PWI, especially for those who like math and PWI.
So, here's the problem:

Ancient Evil: Lethal Vengeance
Assuming now Lethal Vengeance has the following drops distribution:
Drops                                                                                                            Probability
1 Ancient Devil's Soul  +  3 Ancient Devil's Horn + 6 Stone of Sacred Temple            - 3%
1 Ancient Devil's Soul  +  3 Dust of Devil            + 6 Stone of Sacred Temple            - 3%
3 Ancient Devil's Horn  + 3 Dust of Devil            + 3 Stone of Sacred Temple             - 9%
                                                                     9 Stone of Sacred Temple             - 85%

Suppose you want to collect each type of mats dropped by Lethal Vengeance. How many times do you need to kill Lethal Vengeance on average?

Answer: 20 times

don't get me wrong but something makes me think that you're a secret agent, checking the intellect of mmo players :normal-12: :normal-12:

You are pretty close to the answer, but it is still lower than the answer. Good job because it is so far the closest one to the  correct answer. :D

Lol...Interesting and creative thought! Ofc there's always possibilities, it's just the matter of how high the chance is I am a secret agent spying on the intellects of mmo players...So, do you think how high the chance is?  ;)
