You can put this solution on YOUR website! A jar contains 5 red, 3 green, 2 purple and 4 yellow marbles. A marble is chosen at random from the jar. After replacing it, a second marble is chosen. What is the probability of choosing a purple and then a red marble?
----
P(purple) = 2/14
P(red after purple) = 5/13
----
P(purple and red) = (2/14)(5/13) = 5/91
