The Scribe List
The Scribe List
This is the Scribe list. If a name highlighted in blue the student has already done a scribe for this cycle. You will be expected to scribe once every 30 classes. This link explains the job of a Scribe. Please choose a name from this list as the next person who will be the next scribe.
This is the second round of the scribe list. If you have an * beside your name you did not do a scribe during the first round. You may do a scribe any day you want to catch up. You still will be responsible to do a scribe if you are chosen during round 2.
Part of being a scribe is leaving comments. You will be expected to leave comments behind at the sites provided in the Blogs that scribe link in your side bar.

My first probability post
 Answer one of the question Groups in Full as discussed in class.
Find each probability if you spin the spinner once.
1. P ( red) 1/5 there is 5 options and 1 red. 2. P (green) 1/5 there is 5 options and 1 green. 3. P (blue or white) 2/5 there is 1 blue and 1 white and their is 5 options to pick. 4. P (not yellow) 4/5 there is 5 options and yellow doesn't count. 5. P(not red) 4/5 it has to be yellow, blue, green, white but not red so it doesn't count. 6. P(blue or red or yellow) 3/5 it has to be blue, red and yellow but no white and green.
 Question. What do all the questions have in common. What would you need to know about probability to be successful at solving them.
 Answer. All the questions mostly have the same amount example: 1/5 on red and 4 other colors. You would need to know how to do probability to do this question to do the rest of the 1 first.
 Queston. Are there any common errors students might make when answering any of these questions?
 Answer. They might forget to look at the brackets example: ( Not red) some people might read it quickly and they think it says (red) so they would make the mistake.

Kim's Probability Work=)
3) Solve
16)What is the probability of guessing the correct answer to a mulitple choice question if there are 5 choices?
The pobability is 20%.
explanation: You find this answer by taking the number of outcomes which is "1," and then divide it by the total possible outcome, which is "5."
1/5 = 0.2% * 100 = 20%
17) What is the probability of guessing the correct answer to a true and false question?
explanation: There are only two answers which is true and false so "2," is the total possible outcome. And you can only choose "1," answer so "1' is the number of outcomes.
So make it into a fractionand percent.
1/2 = 0.5% * 100 = 20%
18) what is the probability that your birthday will fall on Saturday or Sunday?
explanation: There are 7 dats in a week, so "7" is your total possible outcome. Saturday and Sunday are only 2 so that's your number outcomes. Make it into a fraction and a percent.
2/7 = 0.2857% * 100 = 28.57%

Master Flash #4
n) If you flip a coin 150 times, about how many times would you expect to get heads?
answer: 75 150/2=75
2 is the T.P.O. so getting a heads should have 50%chance.

c) The letters a, e, i, o, u, and y are vowels. If one letter of the alphabet is chosen randomly, what is the probability it is a vowel?
answer: 6/26 or 3/13
k) If you randomlyu pick a date in April, how many equally likely outcomes are there?
answer: 30
There are 30 days in April so the total possible outcome is 30.
p) A magician asked you to pick a card, any card, from a standard deck of 52 cards. What is the probability of picking an ace?
answer: 4/52 or 1/17
There are 4 Ace in the standard deck so the P.O. is 4/52 or 1/13 .

homework =.=
II Find each probability if you choose one card at random.
#7 P(striped) First you have to find the total possible outcomes which is 8. There are 3 striped squares so the answer is 3/8
#8 P(white) The total possible outcomes for all of these questions is 8 and there are 4 white so the answer is 4/8 , but reducing it will make it 1/2.
#9 P(shaded) there is 1 shaded box P = 1/8
#10 P(white or shaded) there are 4 white boxes and one shaded P = 5/8
#11 P(striped or white) there are 3 striped and 4 white boxes P = 7/8
#12 P(striped or shaded) there are 3 striped and one shaded box P = 4/8 reducing it will make it 1/2
#13 P(not striped) there are only 3 striped, so 38=5 P = 5/8
#14(not white) there are only 4 white so 48=4 P = 4/8 reducing it will make it 1/2
#15 P(striped or white or shaded) there are 3 striped 4 white and one shaded that means that the answer is 8/8 reducing it will make it 1/1

po/tpo
15 boys / 30 students
lowest term
15/30 divide by 15 is 1/2

50%

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.
The objective of the game is to take your bear from the store to their home. To move your bear you use 2 6 sided dice: 1 space  roll 6 or 7 or 8; 2 spaces  roll 4 or 5 or 9 or 10; 3 spaces  3 or 11; rolling a 2 makes you move 2 spaces and gives you another turn; rolling a 12 makes you move 4 spaces but you will lose your next turn. Also the board has different things that will help you go forward or backwards.
The game should be fair since all players can roll different numbers to help them win.

Making a Personal Learning Network
I would like you to create a Personal Learning Network. This is a network of Blogs and other sites that have RSS feeds. You could start with the 5 blogs out of Sargent Park and branch off from there.
Here is a 7 minute screencast that shows you how to set up a Bloglines Account. After you watch it please start to make your own Personal Learning Network. This is the second attempt at making it loud enough. Can you hear me now:)

Why we learn Math
As I was cruising the net looking for something interesting to say I found this movie at Google Movies. The Math Lesson
is the reason why we learn math and need to understand the concepts behind the arithmatic.
Enjoy the show!!
Leave a comment about what you think about this video clip.
