BIG IMPORTANT: Make sure your "chance" answer is in decimal form! If it is 10%, type 0.1 instead of 10! When we play a gacha/gambling game, we always have that one burning question: what's the chance I pull this hot new uber rare unit in just 50 draws?
A quick project I really just made for myself. Some basic statistics, the "event occurring at least once" kind of problem. Hopefully I have the formula down right ><
