To find the probability of drawing an orange marble, we need to know the number of orange marbles in the jar. Unfortunately, you haven't provided the actual table with this information. But, I can help guide you on how to solve this problem regardless.

Let's assume that the table shows the number of marbles of each color. If we have this information, we can calculate the probability.

Step 1: Add up the total number of marbles in the jar. In this case, you mentioned that Rachel has 20 marbles in total.
Step 2: Find the number of orange marbles from the table. Let's say there are 'x' orange marbles.
Step 3: Divide the number of orange marbles by the total number of marbles: x/20.

By following these steps, you can calculate the exact probability of drawing an orange marble.
