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.
