1. ## Help Probability Question Urgent

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.
