Problem 2 (4 points) The Better Business Bureau conducts a survey of 30 people who recently hired an attorney. 17 of them say that they would
recommend their attorney to a friend. 8 say that they would not recommend
their attorney to a friend. And the remaining 5 say that they are not sure.
Three people are selected from this group of 30 people at random (This means
drawing every person with equal probability, but without replacement - the
same person cannot get drawn twice).
What is the probability that
a) All three would recommend their attorney to a friend?
b) The first would not, but the second and third would recommend their
attorney to a friend?
