What Are the Chances?

 Yesterday, your job was to look at this jar of marbles and tell me:
1. What do you notice?
2. What do you wonder?
3. If you closed your eyes and reached into the jar, which colour would you probably pick?

Here's what some of you said: 
Ben - "I see 5 purple and 3 yellow balls. I wonder if they are candy? I think I would pull out a purple one because there are more"
Razeen - "purple because most of them are purple"
Tony - "if I reached in I would get more purple than yellow"
Subhan - "probably I'll get purple because it's the most"
Sukaina  - "purple because there are more purple than yellow"
Sara - "purple because there is more purple gum than yellow gum"
Hassan - "you would probably pull out purple because there are more"

Yes! You are all right! You would probably pull out a purple because there are more purple than yellow. 
In Grade One, we would use math words to explain it like this - you are more likely to pick purple and less likely to pick yellow.

Now, let's try a couple more ... 

Question 1.   
​Which of these are you more likely to pick?
​Which are you less likely to pick?

Question 2
Which colour(s) are you most likely to pick?
Less likely?
​If this was a spinner for a game, would it be a fair spinner?
