1. What is the probability that the spinner will land on blue?

2. In this lesson you will learn how to calculate the probability of an event by creating a ratio.

3. Every event must have an equal probability of occurring.

4. Probability is the likelihood that an event will take place.

5. What is the probability that the spinner will land on blue? 2 3 1 4 8 5 7 6

6. Samuel has a bowl of fruit containing 3 apples, 2 oranges and 5 pears. If he randomly picks 1 piece of fruit from the bowl, what is the probability it will be a pear or an apple?

7. 3 apples oranges 2 + 5 pears 10 fruits total

8. In this lesson you have learned how to calculate the probability of an event by creating a ratio.

9. When you roll a number cube with faces numbered 1, 2, 3, 4, 5, 6, what is the probability it will land on an odd number?

10. 1 A bag has 40 blue chips and 60 green chips. What is the probability that you will randomly pick a blue chip from the bag? 2 A bag has 4 blue marbles, 5 red marbles and 6 green marbles. What is the probability of picking a red or blue marble?

11. Lesson 2

12. In this lesson you will learn how to describe the probability of an eventby using a number line.

13. The probability continuum: certain impossible l l

14. The probability continuum: impossible certain 0 1 l l

15. The probability continuum: l l l 1 0 impossible certain likely unlikely l l equally likely

16. The probability continuum: l l l 1 0 impossible certain likely unlikely l l equally likely

17. The probability continuum: l l l 1 0 impossible certain likely unlikely l l equally likely

18. In this lesson you have learned how to describe the probability of an event by using a number line.

19. There are 12 pairs of socks in Flora’s drawer, 9 are red, 2 are blue and 1 is green. She takes out one pair of socks without looking at the color. Describe (in words) the likelihood of Flora picking out a pair of red socks.

20. A container contains 2 blue, 1 green, and 4 orange and 5 yellow marbles. Find the probability of picking each marble and then put the probabilities in order from unlikely to likely chance of occurring.

21. Lesson 3

22. How can you use the theoretical probability to predict the results from an experiment? If you were to roll a six-sided die 600 times how many times would you predict you would roll a 3 or 6?

23. In this lesson you will learn how to predict the frequency of an event by using the theoretical probability.

24. If you were to roll a six-sided die 600 times how many times would you predict you would roll a 3 or 6?

25. Core Lesson If you were to roll a six-sided die 600 times how many times would you predict you would roll a 3 or 6?

26. In this lesson you have learned how to predict the frequency of an event by using the theoretical probability.

27. If you were to spin 400 times, predict how many times you would land on blue?

28. A bag has 4 blue marbles, 6 green and 2 red. Marcus will pick a marble from the bag and return it 60 times. Of the 60 times predict how many times you would expect Marcus to pick a blue marble?

29. If you were to roll a six-sided die 150 times. How many times would you expect to roll a number greater than 4?

30. Lesson 4

31. How do you find the experimental probability of rolling a 7 based off the table below?

32. In this lesson you will learn how to interpret a set of data by comparing experimental and theoretical probability.

33. Experimental Probability:

34. 1+1 2 5 6 1+6 1+2 1+3 1+4 1+5 3 4 7 2+1 3 2+2 5 2+5 8 4 7 2+3 6 2+6 2+4 4 6 3+4 7 8 3+1 5 3+3 3+6 3+2 9 3+5 4+1 5 9 4+5 4+2 4+4 4+6 7 6 4+3 8 10 5+1 8 5+6 6 10 5+3 5+4 9 5+5 11 5+2 7 6+3 6+4 6+5 6+1 7 6+2 8 6+6 12 9 11 10

35. In this lesson you have learned how to interpret a set of databy comparing experimental and theoretical probability.

36. Results from rolling a six-sided die: • What is the experimental probability of rolling a 4? How does that compare to the theoretical probability?

37. After 60 spins, Chris had the following results: What is the experimental probability of spinning a “B”? How does that compare to the theoretical probability? A B A C C A B B

38. In a survey, Scott asked 50 people if they voted for the current mayor. He recorded the results in this table: Based on the survey, what is the probability that the next person will say “No”? A. 5% B. 20% C. 40% D. 67%
