Getting things organized, and some probability stuff.

Today, we spent the first 10 minutes normally spent on a topic of Mr. Max choice, getting our old tests handed back. That's always a highlight of the class.

Then, Mr. Max gave us some things to think about:
1. Accelerated Math is now "out of" approximately 54 objectives. Where are you?
2. Pre-Test for upcoming Thursday test was handed out last week, have you done all questions?
3. NO CALCULATOR for thursday's test.
Here's what you should know how to do for Thursdays test:
Trig 1 (circular functions)
Transformations
Trig 11 (identities)
Logarithms/Exponential Functions
Perms & Coms
Conics

Now, here's what's left to learn:
1) Probability
2) Geometric Sequences

Here's what we learned today: Probablity
We first learned about sample spacing, which is basically creating a picture about the situation your given. Using ordered pairs, or a chart, or a T chart.


Then we learned about the two different event types, Simple and Compound.
A simple event is when the sample space can not get any simpler then what it is.
A compound event is two or more simple events are considered at once.

Then there's the 2 laws of probablity, first being the addition law, "or". Basically if your trying to find the probability of A or B, you will have to add. The formula is a little more complicated, but its on our formula sheets.

The second law is the multiplication law, "and". When your trying to find the probability of A and B, you will have to multiply. This formula is a little harder to understand, with the whole P(BA) part to it.
We basically spent the rest of the class doing examples.
So, do not forget!!!

Thursday = Test. (Forget your calculator at home kids, we don't need 'em.)
January 14th, 12:30 pm = Pilot exam (10 days after we get back from Holidays.. oh boy. Merry Christmas to us!)
Thats about it! Good luck everyone! Study it up!
