## Roll up the Probability Possibilities

A couple of years ago i posted a running total of my roll up the rim to win coffee purchases. i wanted to see if the 1 in 9 chance would actually occur in my own purchases, while also being aware of the geographical inconsistencies in which Tim Hortons distributes its winning cups. This allowed my students and i to engage in conversations around a real-life example of probability. It was fun, (and it may actually resulted in a few coffees being purchased FOR me by some students and their parents — wink, wink.) So i will continue this practice on the Six Nations Numeracy blog this year. Tim Hortons claims a 1 in 6 chance of winning this year, as they have added more prizes.

However, one factor i didn’t anticipate that may have “skewed” the results, were those instances where i actually purchased the coffee, but as a gift for someone else. Did those winning cups count towards my total? Is that why my actual buying experience didn’t concur with Tim Hortons’ alleged odds? So this year, i will include any winning cups i bought for others. Maybe good karma has its way of working and messing with probability?
Drinks for me: 23
Drinks for others: 6
Drinks for me, purchased by others: 4
Total Drinks Purchased: 33
Winning cups for me: 2
Winning cups for others: 2
Winning cups for me, purchased by others: 0
Total winning cups: 4
Odds for me: 2 in 23
Odds for others: 2 in 6
Odds for me, purchased by others: 0 in 4
Total odds: 4 in 33

## 100 Ants for 100th Day

Thinking of a literacy/numeracy activity for your 100th day celebrations?

Try searching for lesson plans written for the book, One Hundred Hungry Ants.
Click here to preview the book. It was recently in Scholastic’s book order for February and can still be ordered through them.
Sorry, grade 8s. You’ll have to do your own search. (Or how about having the grade 8 students TEACH one of the lessons above TO a lower grade? To teach something requires a lot more mastery of the subject.)
