Find the probability of getting at least three defective items in a batch of ten items if the overall percentage of defects is 40%.
Ok, so this is my question "at least 3" so i am using my TI-84 plus clac. and i make a table by using binompdf(n,p) and putting it in list 1.
It gives me this
so if i want to know the probablity of at least 3 what do i do with these numbers?
