1.You flip a coin 30 times and get heads 11 times, so the chance of getting heads is 11/30. Is this an example of theoretical or experimental probability?
theoretical
experimental *
2.You have made 3 out of 10 of your last free throws. How many free throws can you expect to make if you shoot 100 free throws?
30 *
50
60
75
my choices are marked with a * ...thanks
I agree with your answers.
Thank you Ms. Sue
Thats wrong
yes those are right

1. The first question is an example of experimental probability. Experimental probability is based on actual results obtained from conducting an experiment or observation. In this case, the experimenter flipped a coin 30 times and observed heads 11 times. Therefore, the chance of getting heads (11/30) is derived from the actual experiment rather than from a theoretical expectation.
To answer this question in the future, you can determine whether the probability is theoretical or experimental by asking yourself if it is based on actual observed outcomes (experimental) or based on mathematical calculations or assumptions (theoretical).
2. To determine how many free throws you can expect to make if you shoot 100 free throws, you can use the ratio of successful free throws to the total attempts you've made so far.
In this case, you've made 3 out of 10 free throws, which means your success rate is 3/10. To find out how many successful free throws you can expect out of 100 attempts, you can set up a proportion:
(3/10) = x/100
Cross-multiplying, we get:
10x = 3 * 100
Simplifying, we find:
10x = 300
Dividing both sides by 10, we find:
x = 30
Therefore, you can expect to make 30 out of 100 free throws.
In the future, to determine how many free throws you can expect to make, you can use the proportion method and apply the success rate to the total number of attempts.
