..been having trouble when there are two random selections rather than one. heres the problem:
there is a survey of people that can name three movies but only 17% can name at lesat three justices in a court. Suppose two people are selected at random.
So what is the probability that both can name the three movies? Mr F says: Let me get this straight. You're asking what is the probability that a person can name 3 movies when that person is chosen from a group that can name 3 movies ....
then what is the probability that both can name atleast three justices in court? Mr F says: (0.17)(0.17).
also, what is th eprobability that atlesat one of them can name at least three justices in court?
are these independent events?? Mr F says: Pr(at least 1) = 1 - Pr(none).
thanks for any help.
