Probability Question

Anna flips a coin and spun the spinner , organize all the possible outcome in a chart or a tree diagram that shows the sample space.


- are the events independent events .

Organizing Outcomes

ORGANIZING OUTCOMES


There are two ways to organize an outcome :
1) first way is to make a chart or a table

favourable outcome
possible outcome    

Independent events- the outcome of one event has no effect on the outcome of another event
EXAMPLE:

Sample space- all possible outcomes of an experiment EXAMPLE:




12 possible outcomes in this probability ( sample space)


2) the second way to organize outcomes

Tree diagram- a diagram used to organize outcomes contains a branch for each possible outcomes


EXAMPLE:

Pages 4-6 question and answers

Text Book ( 4-6)


4. Determine the area of each parallelogram. they are drawn on the cm grid paper.




A) if you look at A you can see that the base = 4 cm and the h = 1 cm so if you multiply 4 x 1 = 4cm*




B) if you look at B you can see that the base = 3 cm and the h = 3 cm so if you multiply 3x3 = 9 cm*








5. Draw each of the parallelograms on a centimetre grid paper. Check your answers using estimation.


B) b = 3 cm h = 7 cm





6. Draw each parallelogram cm grid paper. Determine each area using the formula. Check your answer using estimation.


A) h = 6cm,b = 4cm  

B) h = 2cm,b = 4cm

order of operation

order of operation
this is what you have to know when you are working with the order of operation: 


B-brackets - when you have a question with brackets you work on the brackets first.
E-exponents - Then next you work on exponents
D-division -Since division and multiplication are like mom and dad which ever comes first is what you work on first.
M-multiplication
A-addition - Since addition and subtraction are like brother and sister which ever comes first is what you work on first.
S-subtraction








solutions to the 3 questions:

  1. Annie has been asked to calculate 1.7+6 divided by 2.She claims the answer is 3.85.Do you agree? explain why or why not. i don't agree because if you use BEDMAS you would have 4.7.
  2. Put bracket in the following expression to get the largest value as possible. 3x(2.8)+(6.4)divided by 4=10.9.
  3. Create a problem that could be solved using the following expression. (2.5+1,25)+(5x1.6)=14.














order of operation

Order Of Operation
When you are working with order of operation you have to know:

B-brackets so if there are bracket around a question you do that first.
E-exponents then you have do exponents next.
D-division after you have to look for division or multiplication which ever one comes first 
M-multiplication
A-addition finally you have to look for addition or subtraction which ever one comes first.
S-subtraction
 E.G.


Solutions to 3 Questions:

  1. Annie has been asked to calculate 1.7+6 divided by 2.She claims the answer is 3.85.Do you agree?  i don't agree because if you use BEDMAS you would divided the answer first 6 divided by 2= 3 + 1.7 =4.7 
  2. Put brackets in the following expression to get the largest value as possible.What problem solving did you use?     3x(2.8)+(6.4)divided by 4=10.9
  3. Create a problem that could be solved using the following expression. (2.5+1.25)+(5x1.6)=14
