(06.05 hc) 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.
