if there is gonna be 100 cookies an 400 raisins in the batch there should be a 1% chance that no 1 or more cookie will come out with out raisins. You have more raisins than the number of cookies which if u ever bake cookies when adding in things like that you should add in as much raisin as there is cookie.
