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

Best ResponseYou've already chosen the best response.0What 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.

Best ResponseYou've already chosen the best response.1experimental probability is what they got (in the table) theoretical probability is "theory" if you have two sides, and are equally likely to get one as the other and you toss the coin 100 times, what is the theoretical number of heads you will get? any idea?

Best ResponseYou've already chosen the best response.1if a coin is fair, and you toss it 100 times, do you expect to get 100 heads and no tails?

Best ResponseYou've already chosen the best response.1the coin has one head side and one tail side, and "in theory" you should see the same number of heads and tails.

Best ResponseYou've already chosen the best response.1if you toss the coin 100 times, theory says you should see an equal number of heads and tails. in other words, 1/2 of the 100 will be heads and 1/2 of 100 will be tails

Best ResponseYou've already chosen the best response.0so would my answer be one of the first two? cause thats what im thinking.

Best ResponseYou've already chosen the best response.1yes so 50 50 is the theoretical number of heads and tails for group D if you toss the coin 50 times, how many heads do you expect (in theory) ?

phi

Best ResponseYou've already chosen the best response.1yes, and 25 tails so here is what we have group C theory 25 25 expt 31 19 groud D theory 50 50 expt 51 49
