When 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?
Correct. 1/2 is also 50 %
Now look at the two experiments.
For 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?
No. To find what percentage 34 is of 50, divide 34 by 50 and multiply by 100. 34/50 * 100
Good. 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?
Good. Now we have this: Experimental Theoretical Experimental Theoretical Heads Heads Tails Tails Group G 68 50 32 50 Group H 51 50 49 50
Now look in the table above, read all choices, and choose the correct choice.
A. 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.
B. 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.
Group 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,
C 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?
