Quizplus · Accepted Answer

Since the program evenly enrolls undergraduate and graduate students, the probability of selecting an undergraduate student is 0.5.

Thus, the probability of selecting four undergraduate students in a row is 0.5 * 0.5 * 0.5 * 0.5, which equals 0.0625 or 6.25%.

Therefore, the correct answer is choice B.
