3. 10-2 Experimental Probability Experimental probability is one way of estimating the probability of an event. It is based on actual experience or observations. Experimental probability is found by comparing the number of times an event occurs to the total number of trials, the times an experiment is carried out or an observation is made. The more trials you have, the more accurate the estimate is likely to be. Course 2
4. 10-2 Experimental Probability EXPERIMENTAL PROBABILITY probability number of times an event occurs total number of trials Course 2
5. 10-2 Experimental Probability Additional Example 1: Sports Application During skating practice, Sasha landed 7 out of 12 jumps. What is the experimental probability that she will land her next jump? P number of times an event occurs total number of trials number of jumps landed P number of jumps attempted 7 Substitute. 12 The experimental probability that Sasha will land her next jump is 7 . 12 Course 2
6. 10-2 Insert Lesson Probability Experimental Title Here Try This: Example 1 During basketball practice, Martha made 9 out of 10 free throws. What is the experimental probability that she will make her next attempt? P number of times an event occurs total number of trials P number of free throws made number of free throws attempted 9 10 Substitute. The experimental probability that Martha will make the next free throw is 9 . 10 Course 2
7. 10-2 Experimental Probability Writing Math “P(event)” represents the probability that an event will occur. For example, the probability of a flipped coin landing heads up could be written as “P(heads).” Recall that an outcome of an experiment can be impossible, certain, or in between. If an event is impossible, it will never happen in any trial. P(impossible event) = 0 total number of trials =0 0 divided by any number except 0 equals 0. Course 2
8. 10-2 Experimental Probability If an event is certain, it will always happen in every trial. This means that the number of times the event happens is equal to the total number of trials. P(certain event) = total number of trials total number of trials =1 Any number except 0 divided by itself equals 1. Course 2
9. 10-2 Experimental Probability All probabilities can be expressed numerically on a scale from 0 to 1. As likely Impossible Unlikely as not Likely Certain 0 1 1 2 Course 2
10. 10-2 Experimental Probability Additional Example 2A: Application Students have checked out 55 books from the library. Of these, 32 books are fiction. A. What is the experimental probability that the next book checked out will be fiction? number of fiction books checked out P(fiction) total number of books checked out 32 Substitute. 55 The experimental probability that the next book checked out will be fiction is approximately 32. 55 Course 2
11. 10-2 Experimental Probability Additional Example 2B : Application B. What is the experimental probability that the next book checked out will be nonfiction? P(nonfiction) number of nonfiction books checked out total number of books checked out 23 Substitute. 55 The experimental probability that the next book checked out will be nonfiction is approximately 23. 55 Course 2
12. 10-2 Insert Lesson Probability Experimental Title Here Try This: Example 2A Students have a fruit choice for lunch of an apple or a pear. So far 18 of 47 students have selected pears. A. What is the experimental probability that the next fruit selected will be a pear? P(pear) number of pears selected total number of fruit selected 18 47 Substitute. The experimental probability that the next fruit selected will be a pear is approximately 18. 47 Course 2
13. 10-2 Insert Lesson Probability Experimental Title Here Try This: Example 2B B. What is the experimental probability that next fruit selected will be an apple? number of apples selected P(apple) total number of fruit selected 29 Substitute. 47 The experimental probability that the next fruit selected will be an apple is approximately 29 . 47 Course 2
