Bellwork #1
1) In theory, what is the probability of spinning orange?
2) If you spin the spinner 20 times, how many times should you get orange? Prove it with math! Set up a proportion and solve!!
3) If you did this lab yesterday, how many times did your group actually spin orange out of 20 times?

3. Bellwork #2 1) In theory, what is the probability of spinning a 3?
2) If you spin the spinner 24 times, how many times should you get a 3? Set up a proportion and solve!!
3) If you did this one yesterday, how many times did you actually get a 3 when you did the spinner 24 times?
4) Look closely at the spinner. Are all sections the same size? _________ How does this affect the outcomes?

4. Stop and think...
Silently study this chart. Think about this question: How often do you think a sum of 8 happens?
Is it one of the more popular sums (happens more than other #s) or does it happen infrequently (not very often)?

6. Anything But 8 Reflection
How many outcomes are there?
How many outcomes involve rolling a sum of 8?
In theory, what is the probability of rolling a sum of 8? 2 3 4 5 6 7 3 4 5 6 7 8 4 5 6 7 8 9 5 6 7 8 9 10 6 7 8 9 10 11 7 8 9 10 11 12
Theoretical Probability
In theory, you should get one 8 for every 7.2 rolls you do.

7. 5) How many total times did you and your partner roll the dice?
6) In your game, how many outcomes did you and your partner have that involved rolling a sum of 8?
7) What was your experimental probability of rolling a sum of 8 using two dice? Write your answer as a fraction, decimal, and percent!
8) Did your experiment (game) match what was supposed to happen in theory?

8. Anything But 8 Reflection - Extension
9) Based on what we know should happen during “Anything But 8”, what would be a good strategy so that you don’t get your points wiped out? Use math to defend your decision.
In theory, you should get one 8 for every 7.2 rolls you do. 2 3 4 5 6 7 3 4 5 6 7 8 4 5 6 7 8 9 5 6 7 8 9 10 6 7 8 9 10 11 7 8 9 10 11 12

10. Anything But 8 Reflection - Extension
9) Based on what we know should happen during “Anything But 8”, what would be a good strategy so that you don’t get your points wiped out? Use math to defend your decision.
In theory, you should get one 8 for every 7.2 rolls you do. 2 3 4 5 6 7 3 4 5 6 7 8 4 5 6 7 8 9 5 6 7 8 9 10 6 7 8 9 10 11 7 8 9 10 11 12
10) What would it be like to play the game if the rules were changed so that you get a zero when you roll a sum of 2 instead of an 8?
It would be very unlikely to get your points wiped out.

11. SKUNK Game

S K U N K

12. SKUNK Game Reflection How many outcomes are there?
How many outcomes involve rolling a “1”?
In theory, what is the probability of rolling a “1”?
4) In theory, what is the probability of rolling snake eyes?

13. 5) How many total times did we roll the dice?
6) In our game, how many outcomes did we have that involved rolling a “1”?
7) What was our experimental probability of rolling a “1” on either or both dice?
8) Did our experiment match what was supposed to happen in theory?

14. SKUNK Reflection - Extension
9) Based on what we know should happen during “SKUNK”, what would be a good strategy so that you don’t get your points wiped out? Use math to defend your decision.
In theory, you should get a 1 for every 3.3 rolls you do. x x x x x x x x x x x
