WebbStep 1: Construct the probability tree showing two selections. We know there are a total of 9 9 balls in the bag so there is a \dfrac {4} {9} 94 chance of picking a red ball. Then as the red ball is replaced, there are still 4 4 red balls left out of 9 9, so again there is a \dfrac {4} {9} 94 chance of picking a red ball on the second selection.
