4-1: Experiments and Probabilities
Notes: [|Section 4-1 Student 0910.pdf] media type="custom" key="5720527" View a lesson summary here Summary on iTunes

Today we learned how to collect data from experiments using experimental probability. The lesson discussed how to find the relative frequency of how many times an outcome has a chance of occurring. (To find the experimental probability, use P(E)=Number of observations favorable to E/Total Number of observations.) This will give you the percentage of how often something can happen when you move the decimal two places to the right. - Chris P.

Sabrina O.-- In section 4.3 we learned about events, sample space, tree diagrams, fundamental counting principles, experimental and theoretical probabilities. We used the formulas: P(E)= --. The number on top is the number of favorable outcomes. The number on the bottom is the total number. This lesson was fairly simple.

4-4: Probability of Compound Events

 * Student Summaries:** Derrik B. and Katlyn K.- In section 4-4 we learned about Probability of Compound Events. We also talked about mutually exclusive events. A **//__compound event__//** is made up of two or more simpler events. While a **//__mutually exclusive__//** event is when events can not occur at the same time. For example, If you have two events, A and B, that are mutually exclusive, you can find the probability of either A or B by using the formula P(A or B)=(A)+P(B).

4-5: Independent and Dependent Events

Paul R. and Tony Y. - Independent and Dependent Events. First an independent event is if the results of the second event is not affected by the result of the first event. An dependent event is if the result of one event is affected by the result of another event. Dependent is more then 2 things and independent is where you take like 1 spin of a spinner.

4-7: Combinations of a Set
Notes: [|Section 4-7 Student 0910.pdf] media type="custom" key="5871773" View a lesson summary here Summary on iTunes

In this lesson we learned about combinations. A combination is a set of items where the order is not important. For combination the equation is this: n! nCr =. (n-r)! r!
 * Student Summaries:**

The n is the number of different items, and r is the number of items taken at a time. Ps. Everytime I save it the n! and the (n-r)! r! they moves over to the left all the way. By: Kortnee Martin
