Quizplus · Accepted Answer

The probability of getting one head in a single toss is 1/2 (assuming the coin is fair).
Using the binomial probability formula, we can calculate the probability of getting exactly 3 heads in 5 tosses.
P(3 heads) = (5 C 3) x (1/2)^3 x (1/2)^2 = 10/32 = 0.313
Therefore, the answer is D.
