Shannon has a bag of jelly beans. She removed one jelly bean, recording the color, and then replaced it. She repeated the process 44 times and record her results in the table. If she wants her experimental probability to be as close as possible to the theoretical probability of picking a red, what should she do?

• She should do the experiment 44 more times

• She should do the experiment 11 more times

• She should do the experiment 100 more times

• There is no way she can get close to the theoretical probability
