Greg wrote the numbers 1 through 9 on pieces of paper and placed them in a hat. He will randomly select one
piece of paper from the hat. He will not replace it. Greg
will then randomly select a second piece of paper from
the hat. What is the probability that Greg will select a
piece of paper with an odd number on it and then select
one with an even number on it?
