In which scenario is the experimental probability equal to the theoretical probability?

a. A coin is flipped six times, and the head appears three times.
b. A coin is flipped six times, and the head appears five times.
C. A coin is flipped six times, and the head appears each time.
d. A coin is flipped six times, and the head appears four times.

Scenario c. A coin is flipped six times, and the head appears each time. In this case, the experimental probability of getting a head is equal to the theoretical probability of getting a head, as each flip results in a head.
