Probability

We rolled two dice. We worked out the sum of the dice. We knew that the lowest sum possible sum was 2 by rolling a 1 + 1, and the highest possible sum was 12 by rolling a 6 + 6.

What was the probability of rolling a 12? Was it the same chance as rolling a 7?

Each group recorded their scores on tally charts. We them compiled the groups totals on a spreadsheet. From the spreadsheet we created a bar graph.


We learned a lot about how to make different types of graphs.





The chances of getting a 12 are a lot less than the chances of getting a 7.
To get a 12 you have to roll a 6 + 6
To get a 7 you can roll

• 1 + 6
• 2 + 5
• 3 + 4
• 4 + 3
• 5 + 2
• 6 + 1

We then repeated the activity with 3 dice
