1. Warm up Given the data points, create a stem and leaf plot and a box and whisker plot: 3, 5, 11, 34, 28, 19, 4, 6, 14, 17, 22, 30, 1, 1, 9, 10, 24, 27, 33, 20, 9, 4

2. Answer 1, 1, 3, 4, 4, 5, 6, 9, 9, 10, 11, 14, 17, 19, 20, 22, 24, 27, 28, 30, 33, 34 Median: 12.5 Q1: 5 Q3: 24

3. Probability 11.1

4. What is Probability? The likelihood that an event will occur Can be summed up as “Success Over Total”

5. Theoretical vs Experimental Probability Theoretical Probability: when you consider all of the possible outcomes and each is equally likely. Experimental Probability: when you actually conduct trials and consider the data to determine the probability. Both methods boil down to “Success over Total”

6. Example Find each probability You roll a six sided die: P(2)=P(even)= P(less than 5)=P(0)= P(less than 7)=P(1 or 2)=

7. Fundamental Counting Principle How many possible outcomes are there if you flip two coins, and roll a number cube (die)?

8. Example If I want to purchase a hat and there are 5 different colors, 4 different logos, and 3 different styles, how many different hats do I have to choose from?

9. Example

10. You toss a coin and roll a number cube. What is the probability that the coin shows tails and the number cube shows 4?

11. Odds Odds for: Success to not Success Odds against: not success to success

12. Spinner results: Red: 5 Green: 9 Blue: 3 Yellow: 3 Odds for Red= Odds against Blue = Odds for Yellow = Odds against Green=
