I'm sorry but that is not how binomial probability distribution calculated.

1. As said above by Meiqi, the drop rate is at a fixed constant of 1.15%+/-, and prior runs don't affect the consecutive runs. Whether you get Higekiri or not is decided should you got an A or B on final wave, for instance which stimulated by 100 faced die(singular word for dice) which one of it represents Higekiri. While doing more runs only increase the likehood for you to hit that Higekiri's spot, but it still doesn't change the fact the drop rate is at 1.15%+/- all the time, considering that thi is an RGN game. Some may even be lucky enough to received Higekri on fewer runs (including me) but there are some who doesn't get any after countless of run.
