Best ResponseYou've already chosen the best response.0When you toss a coin, there are two possible outcomes, heads or tails. Each outcome is as likely as the other. When you toss a coin, what is the theoretical probability of landing heads?

Best ResponseYou've already chosen the best response.0Correct. 1/2 is also 50 %

Best ResponseYou've already chosen the best response.0Now look at the two experiments.

Best ResponseYou've already chosen the best response.0For group G and group H, the theoretical probability of landing on heads is 50%. Now let's look at experimental probabilities. In group G there were 50 tosses. There were 34 heads. What percentage is 34 out of 50?

Best ResponseYou've already chosen the best response.0No. To find what percentage 34 is of 50, divide 34 by 50 and multiply by 100. 34/50 * 100

Best ResponseYou've already chosen the best response.0Good. The experimental probability of getting heads in group G was 68%. Now we need to see what the experimental probability of getting heads in groups H was. In group H, there were 100 tosses. 51 of those tosses resulted in heads. Heads was 51 out 100. What percent is that?

Best ResponseYou've already chosen the best response.0A. The experimental probability and theoretical probability for group G is the same. Heads 68 Heads 50 Tails 32 Tails 50 For group G, the experimental and theoretical probabilities are very different. A is not the correct answer.

Best ResponseYou've already chosen the best response.0B. The experimental probability and theoretical probability for group H is the same. Heads 51 Heads 50 Tails 49 Tails 50 For group H, the experimental and theoretical probabilities are a little different. B is not the correct answer.

Best ResponseYou've already chosen the best response.0Group G: Experimental Probability 68 Theoretical Probability 50 Group H: Experimental Probability 51 Theoretical probability 50 Which group has the experimental probability closer to the theoretical probability, G or H? Choose the correct answer from choices C and D,

Best ResponseYou've already chosen the best response.0C states the experimental probability is closer for group G than for group H. What is closer Group G 34 to 50, or Group H 51 to 50?
