    OK so on the first draw.. you put your hand in the bag and there are 4 orange out of the 20 = 4/20 reduced is 1/5 Then.. you put that orange marble back in the bag and you draw again. At that moment there are 4 orange in the bag out of 20 total marbles. So that time when you are it is still 4/20 which is 1/5 So the probablity = 1/5 * 1/5 = 1/25 So you would be able to draw an orange then an orange about 1 out of every 25 times.
