8. Suppose in a class of 40 people, there are 5 people with green eyes, 8 people with blue eyes, 5 people with hazel eyes, and the rest have brown eyes. Consider 9 randomly chosen people from this class, without replacement. Let X be the number of blue-eyed people selected. (a) What is the distribution of X? (b) What is the probability that you draw all of the blue-eyed people? (c) Now consider only two people drawn, rather than nine. Given that the second pick was green-eyed, what is the probability that the first draw was brown-eyed?
