Ok, there are 60 students in a class and there are 40 "good" students. A group of 10 students are sampled independently.
1. Calculate the probability that the group contains more good students than average.
Does this mean calculate P(X>20/3)?
2. The group actually contains 5 good students. Calculate the probability that the sixth student in the group is the theird good one.
I don't even know where to start with this one.
Any help please.
