After learning the theoretical probability of a two-sided coin landing on any one side, students work in groups to flip the coin several times and get the following results: 9 heads and 6 tails. Based on the scenario, which of the following observations made by students about probability is accurate?A.The theoretical probability of a coin's landing on heads, 0.5, is equal to the experimental probability obtained.B. The theoretical probability of a coin's landing on heads is less than the experimental probability obtained.C. The experimental probability of a coin's landing on heads, 0.6, is lower than expected.D. The experimental probability would have been more accurate if the students had decreased the number of trials.
