A jar contains five red marbles and three green marbles. A marble is drawn at random and not replaced. A second marble is then drawn from the jar. Find the probability that the first marble is red and the second marble is green.
Probablility that that first marble is red: [tex]P_{red} = \frac{red}{total}[/tex] [tex]P_{red} = \frac{5}{5+3}[/tex]
Probability that the second marble is green: [tex]P_{green} = \frac{green}{total(new)}[/tex] [tex]P_{green}= \frac{3}{4+3}[/tex] (because 1 red is now gone)
