Chapter 9 Quiz problems and solutions

Hi All,

Please make sure you make ALL corrections on a separate paper and staple it to the back of your quiz.  I am hoping that most of you found your mistakes before this video, RIGHT???????

In addition, you must have your parents sign the quiz by the grade.  Remember, you make take a retake if you do some remedial work on the section you missed.

All three of these beauties being to Dahlia!! I really like the kitttie and the other 2 - well...... 

I am sure  you will all like them!!

Probability- Permutations lesson 6

Hello Girls and Boys,

So, I hope you all did a fine job on your first math quiz...... open notes and calculators are always a help and so practical.  Today we are moving onwards to PERMUTATIONS! A big word in probability that means that the order of something matters!!! As in a a game - there could be a first , second and third place winners.  We will go over this in class and use the vocabulary to be and sound like mathematicians!  

This sweetie is Pepper!  She OWNS Tess!! She certainly has found a soft spot to lay down. 

Homework:  Read the blog, watch the videos, take notes in your graphic organizer, and vocabulary needs to be defined in your Ribbon Book!

Probability - Fundamental Counting Principle

Good Evening Girls and Boys,

We are skipping lesson 4 for now and jumping into lesson 5, The Fundamental Counting Principle.   The Fundamental Counting Principle sounds very complicated but in reality, it makes probability a lot easier.  From lesson three we learned about the Tree Diagram and tables to solve the outcomes of compound events and most if not all of you were finding this fairly good.  Well, I have great news for you, today we are learning about a shortcut in getting the outcomes of events with the Fundamental Counting Principle.  With this method, you simply MULTIPLE the outcomes of each event together to get the combined outcomes.  So, if I have and coin and cube- the coin has 2 outcomes (heads or tails) and the cube has 6 outcomes(1,2,3,4,5,6)- You multiple 2 x 6 and get 12 outcomes for the compound events.  I think you will find this far easier.  Let me know what you think in your working spirals!

These three kitties are so lucky to have Julia for an owner! Or do they own her?!!! Love the trio of sweetness.

Homework: Read the blog, watch the videos, take notes in your graphic organizer and write down your vocabulary word- Fundamental Counting Principle.

Probability of a COMPOUND EVENT

Good Evening Girls and Boys,

We have learned about Simple Events from lesson 1, but today we are working on Compound Events!  And just what you would think, a Compound Event consists of at least 2 events !  Another vocabulary word for this lesson is Sample Space.  This is a list of All outcomes for the event.  And the third and last vocabulary for this lesson is Tree Diagram. A tree diagram is a way to organize the Sample Event!  

This little kittie is Jin and she belongs to Alex.  I think she is going to do some vacuuming!

Homework: Read the blog, watch the videos and take notes in the Graphic Organizer (GO) - plus write down the vocabulary terms in your GO.

Probability Lesson 2

Good Evening Girls and Boys,

We still have not sent out your laptops, so we will continue watching these in class.  As always, probability is a language and you must understand the vocabulary.  And if you do so, the math is so much more understandable.  

Our 3 vocabulary terms this lesson are ; Theoretical Probability  Experimental Probability and Uniform Probability Model.

Theoretical Probability is what should happen when you do the Experimental Probability and this should be  random( equally likely to happen ).  Experimental Probability is when you actually DO the experiment.  When you do experiment, if you do not do the experiment long enough, the outcomes may not be random - ( Uniform Probability Model = Random ). So if you do the experiment long enough, the theoretical and experimental probabilities SHOULD equal!

Homework: Read the blog, take notes in your graphic organizer and write down the vocabulary terms.

September 8, 2015 PROBABILITY

Hi Girls and Boys,

As you do not have your laptops yet, you will be reading this blog and watching the instructional videos in class.  And actually, this may be the best thing.  So, get out your GRAPHIC ORGANIZER and start to record everything I write on the screen onto your first lesson note.  Be NEAT and organized as you want to be able to USE this later on.  

This is Penellope, one of our 4 dogs!
I would love to have you email me pictures of your pets or something you would like to share with us!  
Homework: Read this blog, watch the videos and take notes.  Write down the vocabulary terms also.
