There are 10 red, 10 blue, 10 green, and 10 yellow marbles in bag. A student pulled a marble, recorded the color, and placed the marble back in the bag. The table below lists the frequency of each color pulled during the experiment after 40 trials.


Outcome Frequency
red 8
blue 12
green 9
yellow 11


Compare the theoretical probability and experimental probability of pulling a red marble from the bag.
The theoretical probability, P(red), is 20%, and the experimental probability is 25%.
The theoretical probability, P(red), is 25%, and the experimental probability is 20%.
The theoretical probability, P(red), is 50%, and the experimental probability is 20%.
The theoretical probability, P(red), is 25%, and the experimental probability is 8%.
