    Two groups separately performed an experiment by tossing a coin in the air. Group C performed 50 trials and group D performed 100 trials. Each group recorded the results in the table below: Group Heads Tails C 31 19 D 51 49 What conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails? The experimental probability and the theoretical probability for group C is same. The experimental probability and the theoretical probability for group D is same. The experimental probability is closer to the theoretical probability for group C than group D. The experimental probability is closer to the theoretical probability for group D than group C.

    If you tossed a fair coin 50 times, how many heads would you expect?

    If you tossed a fair coin many times, you would expect to get heads about half of the time. Do you agree?

    Good. Then back to my question: If you tossed a fair coin 50 times, how many heads would you expect?

    So you think that if you tossed a fair coin 50 times, it would come up heads nearly every time?

    Yes, you would expect heads about 25 times. In the question group C got heads 31 times in 50 tosses, so the experimental probability is higher than the theoretical probability. However group D got 51 heads in 100 tosses, so the experimental probability is very close to the theoretical probability. Do you understand?
