Find the following probabilities by selecting a marble at random and THEN selecting another marble at random *without* replacing the first marble. First question: What is the probability of selecting 2 marbles at random that are both black? Second question: What is the probability of first selecting a white marble, then selecting a green marble, then finally selecting another green marble? Third question: What is the probability of selecting 5 marbles, all of them white?
