River Walks Last

Riddle: BFJ and BC are beating on Kevin and Ethan in doubles. After Ethan gets decimated, Kevin is on his last stock with 20 secs left on the clock. When all of a sudden, a bunch of magical RNG bs happens. BFJ's luigi hits 11 misfires and BC's peach pulls 5 stitch faces. Luigi's misfire has a 12.5% (or 1/8 chance) chance of hitting, while peaches stitch pull rate is 1.7%. Keep in mind that both did not miss hitting their opponent with any of these, as Kevin has insane sdi and teching abilities and lived through all of them. What is the total percent chance for the misfires and stitches to occur in this match?
