Alg B: Probability Notes and Practice

By Allison Gilbert

Please fill in the notes

You will use this note packet for the rest of the week, so please don't lose it!​

​As you go through the slideshow, please fill in the notes as they appear.

I have included some videos in case you would like to see a visual representation

You may leae y​our note packet in the back of the room in your turn in bin.

Now let's do some practice!

Multiple Choice

• 1/7
• 1/9
• 1/12

Multiple Choice

What is the probability that you choose blue? *simplify your answer*

5 green

6 yellow

8 blue

7 brown

• 8/26

Awesome!

​Now that you have filled in the notes on your own and you have done some practice, please work on ​the IXL skill that is listed on the agenda.
