+22 A bag contains five white b*lls and three black b*lls. Your goal is to draw two black b*lls.
You simultaneously draw two b*lls at random. Once you have drawn two b*lls, you put back any white b*lls, and redraw so that you again have two drawn b*lls. What is the probability that you now have two black b*lls? (Include the probability that you choose two black b*lls on the first draw.)
