Using a mysterious equation to predict how and when he’ll die, a wealthy businessman must kill a corrupt government official to prevent his untimely demise, but when things go awry he starts to question if he is preventing or creating his fate.

I suggest you might want to clarify the theme you want to explore and hopefully that will bring the logline into focus. ?As it currently stands, I am unable to get a handle on either. (Which is complicated by the fact that I had a day job requiring extensive knowledge and intensive use of statistics, so I find it hard to suspend disbelief.)

This seems to be a clone of the sub-genre of stories about futures foretold through story props like astrology charts, tarot cards, crystal balls, etc. ?The prop may be different but premise seems to be the same. ?Other than the prop, what does this story bring to the sub-genre that hasn't been done before?

Try to reword 'mysterious equation' in a way that express mystery without the word mysterious and in a way that is fully undestandable. Where does he find this equation? There's a book about this, 'The Stochastic Man': the main character is a statistics expert, maybe the 'equation' is advanced statistics?
