D Correct answer
Explanation

The probability of getting no head in one toss is 1/2. For five tosses, it is (1/2)^5 = 1/32.

AI explanation

The total possible outcomes when a coin is tossed 5 times is 2 raised to the power of 5, which is 32. Getting no heads means getting all tails, which is exactly 1 favourable outcome (TTTTT). Using the classical probability formula, the probability is 1 divided by 32. The result is 1/32.
