1 Warm Up Problem of the Day Lesson Presentation Lesson Quizzes

2 Math Journal (5 Min) Each student will be given the title of the lesson that will be taught that day. They must then, at the beginning of class, write 3 statements that they already know about the lesson being presented, 2 questions that they have before the lesson is presented, and 1 connection that they feel can be made between what they already know and what they think they will be taught in the new lesson before they have been taught the lesson, and at the end of class, write 3 statements that they now know about the lesson being presented, answer the 2 questions that they had written previously, and 1 connection that they now know can be made between what they knew before the lesson and what they now know after they have been taught the lesson. Then, each student will discuss his/her answers within their group. Finally, to leave class, each student will have to give/write 1 statement or connection that pertained to the lesson.

3 Homework Review (5 Min)

4 Warm Up 1. A jar contains 6 red, 8 blue, and 10 white marbles. Would you be more likely to pull out a red or a blue marble? Determine if the event is impossible, unlikely, as likely as not, likely, or certain. 2. Attendance at a city council meeting is at 100%. Mr. Lloyd is a council member. How likely is it that Mr. Lloyd is at the meeting? blue certain

5 The probability of Liana making a free throw was
Problem of the Day The probability of Liana making a free throw was 2 3 . If she made 24 of her free throws, how many did she miss? 12

6 Textbook Examples (I Do) (5 Min)

7 Learn to find experimental probability.

8 Vocabulary experimental probability

9 Experimental probability is one way of estimating the probability of an event. The experimental probability of the event is found by comparing the number of times an event occurs to the total number of trials. The more trials you have, the more accurate the estimate is likely to be.

11 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(event)  number of times an event occurs total number of trials number of jumps landed number of jumps attempted P(jumps landed)  7 12 = Substitute data from the experiment. The experimental probability that Sasha will land her next jump is . 7 12

12 “P(event)” represents the probability that an event will occur
“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).” Writing Math

13 number of times an event occurs total number of trials
Check It Out: 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(event)  number of times an event occurs total number of trials P(free throws made)  number of free throws made number of free throws attempted 9 10 = = 90% Substitute data from the experiment and write as a percent. The experimental probability that Martha will make the next free throw is or 90%. 9 10

14 Additional Example 2A: Application
Students have checked out 55 books from the library. Of these, 32 books are fiction. What is the experimental probability that the next book checked out will be fiction? number of fiction books checked out total number of books checked out P(fiction)  32 55 Substitute data. The experimental probability that the next book checked out will be fiction is approximately 32 55 .

15 Additional Example 2B: Application
What is the experimental probability that the next book checked out will be nonfiction? P(fiction) + P(nonfiction) = 1 Use the complement. 32 55 + P(nonfiction) = 1 Substitute. Subtract from both sides. 32 55 32 55 P(nonfiction) = 23 55 Simplify. The experimental probability that the next book checked out will be nonfiction is approximately 23 55 .

16 number of pears selected
Check It Out: Example 2A Students have a fruit choice for lunch of an apple or a pear. So far 18 of 47 students have selected pears. 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 data. The experimental probability that the next fruit selected will be a pear is approximately 18 47 .

17 What is the experimental probability that
Check It Out: Example 2B What is the experimental probability that next fruit selected will be an apple? P(pear) + P(apple) = 1 Use the complement. 18 47 + P(apple) = 1 Substitute. Subtract from both sides. 18 47 18 47 P(apple) = 29 47 Simplify. The experimental probability that the next fruit selected will be an apple is 29 47 .
