A large bag contains 16 red, 48 blue, and 16 green marbles. Each student in Mrs. Wynn's class randomly selects a marble, records the color, and then puts the marble back into the bag. Mrs. Wynn then reports the total number of red, blue, and green marbles selected by the entire class. Which of these statements are true? Choose all that are correct.

A.
Theoretically, the probability of selecting one red marble from this bag is 0.20.

B.
If a student does not return his or her marble to the bag before the next student selects his or her marble, the theoretical probability of selecting a blue marble may be different for the next student.

C.
If there are 30 students in the class, the total number of blue marbles selected should be about 18 but may be more or less.

D.
It is possible that every student selects a green marble.

E.
If the total number of red marbles selected is not equal to the total number of green marbles selected, then there was a mistake in selecting the marbles or recording the data.
