heello !
Well today we didn't really do anything but TLE .
Oh and , for the people who haven't done TLE yet , the subject we had to do is
Rates and Ratio's .
Since I forgot to do yesterday's blog , I'm going to talk about yesterday's math . Yesterday , the number of the day was 7835.621 .
Mr.Isfeld told us to work on our text book work , page 198 questions 2 - 14 .
We had to do these Probability tree's and tables .
For example , if you were to flip a coin and roll a die , what are the possible outcomes that the coin will land on heads and the die to roll a 4 ?
First , you would have to make a Tree Diagram for the die .
It might look like this :
A probability tree diagram shows all the possible events.
The first event is represented by a dot.
From the dot, branches are drawn to represent all possible outcomes of the event.
The probability of each outcome is written on its branch .
Then , for the coin , you need to draw a Table Diagram .
Which would look something like :
Sample space:
{ H1, H2, H3, H4, H5, H6,
T1, T2, T3, T4, T5, T6 }
The probability of each of these outcomes is 1/2 • 1/6 = 1/12
And to end this off , I am going to ask a probability question ,
and you must answer it in the comments box .
An ice chest contains 9 cans of apple juice , 8 cans of grape juice , 7 cans of orange juice , and 5 cans of pineapple juice . If you reach into the container and randomly select 3 cans from the chest , what's the probability of selecting no grape juice ?
For the next post , I choose .. DARNELL .
