Have a nice Break!!

Project Presentations

In class students presented their projects on Collecting Data.  There is no homework.

Probability Models

In class students continued to create probability models and find mean (expected value) and standard deviation of problems involving discrete random variables. 

The notes are attached and the homework is listed below.

Quiz - Basic Probability

In class students took a quiz on basic probability.  Afterwards, students began working on probability models for discrete random variables.  We will continue this discussion on Monday.  For homework, work on your projects.

Basic Probability Review

In class we reviewed chapters 14 and 15 on basic probability. 

The class notes are attached as is the practice quiz and answer key.  The homework is listed below.

Conditional Probabilities - Tree Diagrams

In class students reviewed how to use Venn diagrams and contingency tables to find probabilities.  Afterwards, students learned that when given a conditional probability, one should use a tree diagram to find other probabilities.

Things to Remember.

            1.  "Replacement" or "Without Replacement?"
            2.   Use Venn or Contingency table when given basic probabilities.
            3.   Use tree diagram when given conditional probabilities.
            4.  Be familiar with formulas but use graphic organizers to answer questions.
            5.  "At least one" or "some" means...1 - none.
            6.  Define/differentiate disjoint/mutually exclusive and independent...and prove
                 independence P (A|B) = P(A)

Probability Cont.

In class students continued learning about probability.  Students learned about 2 graphic organizers that can be used to answer questions involving probability:

1) Venn Diagram - disjoint/mutually exclusive, A ∩ B, A ∪ B.
2) Contingency Table - can answer all questions involving probability.

The homework is listed below and the notes are attached.

Notes - Probability Cont.

HW - Complete pgs. 361-363 (1-11 odd) - draw a Venn/Table for each question (good practice!)
          Read pgs. 353-360

Formal Probability

In class students were introduced to the basic probability rules.  Students should be familiar with and able to differentiate between disjoint/mutually exclusive and independent.

Students should also remember when a question asks for "at least 1" or "some" that means 1 - none.


The notes are attached and the homework is listed below.
