Hey here are today's notes

Tomorrow is a test. You need to know theoretical probability, experimental probability, probability trees and a few other things. You do not need to know about independent and dependent probability.

Probability Game

Here is the game from today's class.



It is a live link. Go and play the game. Make the game fair and unfair.

Online Probability Tutor

Tonight's homework comes to us from Alberta. This is a great little activity on Probability. Click the picture and go to the site. After the introduction click lessons on the menu and then find Lesson 19. Here you be given a guided tour of probability. Once you are done the lesson....

... you will be able to practice calculating theoretical probability on the worksheets you have for homework.

Enjoy

Do you remember probabiliby

Mrs. Simpson has a great problem at her site.

I would like you to answer it here and copy and paste your answer into her blog here.

In the Gee Whiz Everyone Wins! television game show, members of the studio audience draw a block randomly from a bucket containing 2 red blocks, 1 yellow block, and 3 blue blocks. If a blue block is drawn, the contestant wins $5. If a red block is drawn, the contestant wins $10. If the yellow block is drawn, the contestant wins $50. The block is replaced after each draw.

a. What is the probability of drawing each color?

b. If 24 contestants draw a block from the bucket, how much money can the game show expect to pay out?

Remember Answer the question here and at the Alabama Blog Site.

Using Flickr to add pictures to your Probability Post

Flickr is a online digital photo service. If you take digital photos you can create an account here and upload your phots'. It is also the place where I put the pictures of your Probability Games.

You do not need a flickr account to access these photos. Here is how you will find what you need.

1. Go to Flickr.
2. In the box called Find Picture type in charbeck10(this is my account) It will not work but will take you to the next page. Click on the button people and type charbeck10 again.
3. When you find my pictures go to your rooms set of game boards.
4. Find your game board.
5. Download it to your hard drive and then upload it to blogger.
6. You can now use this picture in your blogpost.

Good luck

Probability Assignment 2

Here is the second assignment you have to add to your first post. Please at the end of your first post create a title Fun and Games and complete the following questions as demonstrated in class.

Fun and Games

You and some classmates need to create a game for a booth at the school carnival. The game should be easy to make and set up. I should be fun, too, but it mustn’t take long to play. Of course the game must be fair. This means that any player would have about the same chance of winning as losing.

Explain the rules of your game. Tell why it would be fair and fun. Use Probabilty to prove your rules are fair.

Play your game 10 times. Record your results. Is it really a fair game?

Here is the Scoring Guide for this Assignment

Instructions 5 Marks	Above Expectations Perfectly understandable Instructions	At Expectations Instructions are missing some information.	Some Effort Instructions are hard to understand	No effort Below Expectations No Instructions
Rules 10 Marks	Rules are fair. Probability is explained in the rules.	Rules are fair. Probability is partally explained	Rules are not fair. Probability is not explained in enough detail.	Rules are fair. No probability is involved.
Game Board 5 Marks	Game board or game is artistic and creative.	Game board or game has had some effort in its creation.	Game board was done at the last minute and shows little effort.	Game board or game shows a lack of pride or effort.
Extra 5 Marks	Above and beyond the call of duty. In all aspects of the game board, probability and clarity of instructions.	Less than above.

Look what you can find on probability

Here are some excellent sites to practice probability. Many are interactive and expect you to read and then try some activities. Try them you might like them.

Probability Movie

Here is a movie that explains probability.

Probability Lesson

Here is a brief lesson on about Probability. It is fun and interactive. what do you think?

Now watch this Video.
Now try this interactive activity.

Interactive Spinner

Here is an interactive spinner. Can you use it to help you determine the difference between Theoretical probability and Experimental Probability?

Crazy Choices Game

Here are the instructions for the Crazy Choices Game. Use this to determine the difference between theoretical and Experimental Probability.

How do you know your game is fair.

Try these two activities using the Crazy Choices Game.

Probability Problems

Here are the 4 problems that were presented in class today. Please be able to explain 2 of these to the class. One question must be question 4 and you can choose one of the remaining questions.

Probability
(Answer ID # 0738518)

Complete.

1. You are playing the �shell� game. In this game, there is object (let�s say a coin) hidden under one of three cups and you have to try and guess which cup it is under. Assuming the game is fair and there are three cups, what is the probability you will guess correctly on the first try?

2. If you flip a fair coin six times and it comes up heads each time, does this mean that for some reason the probability of getting heads is greater than the probability of getting tails on that particular day?

3. Isaac thinks of a whole number between one and twenty-four. He then asks his mom to guess what number he is thinking of. Assuming Isaac is not known to have any number preference or predictable pattern to his number picking, what is the probability that his mom will correctly guess what number he is thinking of?

4. Amber bought a bag containing assorted hard candies from the local corner store. They were on clearance and she got a good deal. All the candies are the same size and shape but they are different colors and flavors. There are five blue ones, two red ones, three purple ones, eleven green ones, and five orange ones. If the bag is shaken really well to mix the candy in the bag, what is the probability that the first candy she pulls out of the bag will not be green?

Some Probability Homework

Here is a link for the questions we had in class today.

Here are the questions.

Find the probability.

1. A number from 18 to 25 is drawn at random. P(22, 24, or 21) Express the probability as a percent. Round to the nearest percent.	2. You roll a number cube numbered from 1 to 6. P(not a 1) Express the probability as a fraction.
3. A jar contains 11 black, 24 red, 25 orange, and 10 pink marbles. A marble is drawn at random. P(orange or black) Express the probability as a decimal. Round to the nearest hundredth.	4. You roll a number cube numbered from 1 to 6. P(a prime number) Express the probability as a decimal. Round to the nearest hundredth.
5. A number from 9 to 21 is drawn at random. P(14) Express the probability as a percent. Round to the nearest percent.	6. You roll a number cube numbered from 1 to 6. P(a number divisible by 3) Express the probability as a fraction.
7. A jar contains 4 blue and 17 black marbles. A marble is drawn at random. P(not blue) Express the probability as a decimal. Round to the nearest hundredth.	8. A jar contains 24 black and 6 purple marbles. A marble is drawn at random. P(black) Express the probability as a percent. Round to the nearest percent.
9. A number from 10 to 16 is drawn at random. P(a number greater than 16) Express the probability as a fraction.	10. A jar contains 26 red and 8 pink marbles. A marble is drawn at random. P(red) Express the probability as a fraction.
11. You roll a number cube numbered from 1 to 6. P(not a 4) Express the probability as a decimal. Round to the nearest hundredth.	12. You roll a number cube numbered from 1 to 6. P(2 or 4) Express the probability as a percent. Round to the nearest percent.
