A bag contains 7 purple marbles, 12 red marbles, 3 blue marbles and 3 yellow marbles.
One marble is selected from the bag, replaced, and then a second marble is selected.
Find the Probability:
3/24 (actually you have 25 marbles but we took 24 marbles since 1 has already been taken and then replaced , which means that it's not put back in the bag)
