C Correct answer
Explanation

No tails means two heads. The number of times two heads occurred is 138. Probability = 138/600.

AI explanation

The probability of an event is calculated as the number of times the event occurs divided by the total number of trials. Getting no tails means getting two heads, and the experiment shows this outcome happened 138 times out of 600 total trials. Therefore, the empirical probability is 138 divided by 600. The result is 138/600.
