A bag contains 5 green marbles , 8 red marbles, 11 orange marbles, 7 brown marbles, and 12 blue marbles. You choose a marbles, replace it, and choose again. what is p(red then blue)
20/43
40/43
20/1849
96/1849

since you are replacing the marble, the second draw is not affected by anything you did before.
so Prob(red, then blue) = (8/43)(12/43)
= 96/1849
