Martha is performing a probability experiment. She has a bag of marbles, with each marble colored red, yellow, blue, or orange. She randomly removes a marble, records the color, returns the marble to the bag, and mixes the marbles. She repeats this procedure 100 times. Using the data from the experiment, Martha makes the following predictions:
There are about 2 times as many red marbles as blue marbles.
The probability of randomly removing an orange marble from the bag is about 1/5.
Select the list that could represent the data from the experiment.
A. red 20, yellow 48, blue 11, orange 21
B. red 25, yellow 7, blue 49, orange 19
C. red 16, yellow 49, blue 30, orange 5
