1. Probability Grade 8

2. Skills You’ll Need Jose Bautista hits 13 times in 37 at bats. What is his batting average? What is the formula for experimental probability? What is the formula for theoretical probability? Copy these two formulas in your notebook Homework/Practice: Gr. 7 – p. 406 #1-3 Gr. 8 - P. 454-455 #1-2 Worksheets

3. Probability Range / Listing Outcomes Provide an example of each: o Impossible o Unlikely o Likely o Certain Where would these terms go on a numberline from 0 to 1? Practice p. 460 #8 Practice/Homework: o Gr. 8 - p. 458-460 #1, 3-5, 7, 8, 9 o Gr. 7 – worksheet p. 235-236

4. Theoretical and Experimental Probability Explain whether the following statement is true or false and provide an example to prove or disprove it. The more trials performed for experimental probability the closer it will come to equaling theoretical probability. Extension: Use your response to the problem above to explain the term “the house always wins” which means, in the end the casino wins more than the people gambling.

5. Tree Diagrams / Listing Outcomes If you roll a die and flip a coin at the same time, what are the chances of getting heads and 2. Practice p. 461 “Explore” o Work in partners—each team needs a die and a coin Practice/Homework: Gr. 7 – p. 409-410 #1-8 Gr. 8 - p. 464-465 #2-4, 6

6. Odds For and Against / Theoretical Probability Warm-up: Examine the example on p. 472. o What are the odds in favour of drawing an ace? o What are the odds against drawing a facecard that is a diamond? Practice: p. 471 Explore Practice/Homework Gr. 7 – 418-419 #1-6 Gr. 8 - p. 472-473 #1-7

7. Simulations / Experimental Probability Warm-up: Read p. 468 and explain what a simulation is and how it can be used to solve probability problems. Practice: p. 469 #5 Practice/Homework: Gr. 7 – p. 413-414 #1-7 Gr. 8 - p. 469-470 #3,4, 6ac, 7
