<u>Step 1: Determine the area of the top rectangle</u>
We can tell that the total shape seems like two rectangles glued together. We can separate the top rectangle and determine the area of it and then determine the area of the bottom rectangle and combine them. Lets first solve the left rectangle.
<u>Step 2: Determine the area of the bottom rectangle</u>
These two events are dependent. When the ball is set aside, there are fewer balls to draw from, so the probability of getting a certain ball becomes greater.
