PASSAGE
A student analyzing a probability problem writes: "In a game where I flip a fair coin 3 times, the probability of getting exactly 2 heads is 38\frac{3}{8}. Since there are 3 ways to arrange 2 heads among 3 flips (HHT, HTH, THH), and each outcome has probability 18\frac{1}{8}, the total probability is 3×18=383 \times \frac{1}{8} = \frac{3}{8}."
Evaluate the correctness of the student's reasoning and calculation.
