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 B B B B B G G G G R Put the first marble back. P(red, then green) = 2 G G G R Put the first marble back. P(red, then green) = 3 Y Y Y Y R R R Put the first marble back. P(yellow, then red) = 4 Y Y R R R R G G Put the first marble back.
