Evan is performing a marble experiment in math class. His teacher places an equal number of black, red, blue, and white marbles in a bag. Then, Evan randomly takes out a marble, records the result, and puts the marble back in the bag. Each of the first five times Evan takes out a marble, he gets a red marble.

AWhat is the theoretical probability of Evan picking a red marble next time? Based on Evan's results, what is the experimental probability of Evan picking a red marble next time?

BExplain the difference between the two probabilities you found in part A.

CWhat is the theoretical probability and likelihood of getting five red marbles in a row?
