Write probabilities in simplest form. Example R R R B B B B B P (red) = \frac{3}{8} P (red, then blue) = \frac{3}{8} \times \frac{5}{8} = \frac{15}{64} Think: The marble goes back, so the bag is the same for the second pick: multiply the two probabilities. 1 R R R R R B B B B B Put the first marble back. P(red, then blue) = 2 G G G G R R R R Y Y Y Put the first marble back. P(red, then green) = 3 G G G G G Y Y Y Y R R R Put the first marble back.
