Quizplus · Accepted Answer

There are a total of $2^3 = 8$ possible outcomes when flipping a coin three times. To get exactly two heads, we can have HHT, HTH, or THH, where H represents heads and T represents tails. Each of these outcomes has a probability of $(1/2)^3 = 1/8$. Therefore, the probability of getting exactly two heads is $3 \cdot (1/8) = 3/8$, making the answer D.
