A jar contains two red marbles, three blue marbles, and four green
marbles. Niki draws one marble from the jar, and then Tom draws a
marble from those remaining. What is the probablity that Niki draws a
green marble and Tom draws a blue marble? Express your answer as a
common fraction. (http://mathforum.org/library/drmath/view/56491.html)

Thank you asdert. How does this account for the possibility that Niki may or may not have picked a green marble?
