if you know how to do it when it's >=, then you can calulate it when it's >= 5 and substract it to the total, so you will get for how many solutions it is < 5 or in other words <=4

As for the first problem, i dont remember how to solve such kinda problems and i cant figure it out, so i cant verify if your answer is ok

i see you solved 14!/(14-3)!*3!, but why? I'd like to know
