How can estimating probability be important in real world situations?

1. How can estimating probability be important in real world situations? Question of the day

2. Agenda • Go over quiz • Notes on estimation probability • Lesson 8 exercise • Exit ticket

3. Theoretical vs. Experimental probability while estimating Notes

4. Using estimation in probability • After experimenting with one group, we can use that group to estimate what the outcome would be in another group • If we roll a die ten times and it lands on a two twice. What can we estimate the number of twos rolled if we roll the die 20 times? • P(2)= • =

5. Using estimation between theoretical and experimental • If we know the theoretical probability, we can use that to estimate what would happen in an experiment • If the theoretical probability of flipping a coin and it landing on heads is • P(head)= • How many heads would you expect to land on if you, experimentally, flipped the coin 30 times • =

6. Ideas to remember • Law of large numbers • Experimental probability is the same as relative frequency

7. Assignment • Lesson 8 exercise#1-9

8. Exit ticket • If is rains about 1 day a week, then how many days should it rain in a month. • *assume there are four weeks in a month.
