1. The problem statement, all variables and given/known data If you have a sample of size n=20, where X=the number among the n that are flawed=5, how do you go about finding the probability that the next three chosen will be flawless? do I say (15*14*13*12*11)/ (20*19*18*17*16) . Or is it (15/20)^5? How do I go about solving this?
