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

A. a coin is flipped six times and the head appears four times

B. a coin is flipped six times and the head appears each time

C. a coin is flipped six times and the head appears three times

D. a coin is flipped six times and the head appears five times

B. a coin is flipped six times and the head appears each time

In this scenario, the experimental probability (the number of times the head appears out of the total number of flips) is equal to the theoretical probability (the probability of flipping a head on a fair coin is 0.5, so the theoretical probability of getting a head on each flip is 0.5).
