29.How many four-digit numbers

can you make using the digits

0, 2, 4, and 6 if repetition of

digits is not permitted?

28. A box contains 3 red marbles, 1 black
    marble, and 2 white marbles. Choose one
    marble at random, without replacing it.
    Then pick another marble. What is the
    probability that you would pick a black
    marble, then a red marble?
