**4-1: Experiments and Probabilities**

In a experimental probability you would estimate the likelihood of an event or the desire of an outcome. This is one thing we learned this chapter and this helped us to be able to figure out for example how many times we would get heads or tails if it is tossed 12 times. so you would make a table and recored your data. - Keller H.
 * Student Summaries:**

To find out the experimental probability you would use the formula P(E)= # of favorable outcomes / Total # of possible outcomes, we would use this equation when find the probability of something like a coin toss. This would change when you find the probability using an area model such as a find the probability of hit a bull's eye. You would then replace outcome with the area. -Kayla P.

Problem Solving Skills:Simulations Act it out problem solving strategy is when you physically go through the motions described in a problem or you use objects to represent elements of the problem. A simulation is a model of a situation in which you carry out the trials, collect data, and calculate probabilities. You can use coins, number cubes, spinners or any method that involves random outcomes to do a simulation. - Kailyn H.

What this section is about is Event, Sample space, Tree diagrams, Fundamental counting principle, and Theoretical probability. Sample Space is for a probability experiment is the set all possible outcomes of the experiment. Sample Space is ordered pairs are used to organized and show a sample space. Theoretical Probability can be assigned using the formula below. P(E)=NUMBER OF FAVORABLE OUTCOMES over NUMBER OF POSSIBLE OUTCOMES. For this section all you do to figure out problems you will have to make a tree diagram with the information that you are given. -Tanya H.
 * Student Summaries:**

This section includes using tree diagrams with the information you are being given. You also learn about sample space which is used for probability experiments to show the set of all possible outcomes of the experiment being done. the definition of sample space is ordered pairs used to organize and show sample space. Also in this chapter is Theoretical Probability you do this by using the formula p(e)=number of favorable outcomes over the number of possible outcomes. It also includes Event and the Fundamental Counting Principal. -Sarah L.

**Student Summaries:** This lesson is about Compound Events. A compound event is an event that is made up of two or more simpler events. To find the probability of two things happening we need to find how many outcomes there are. Then figure out the possibility of one of the events happening and do the same with the other. then add those two together and you have your probability of both events happening. - Olivia

4-5: Independent and Dependent Events

**Student Summaries:** this section is based on independent and dependent events as well as finding probabilities.To do this you take the amount that you want to find and divide it by the total amount and you get a fraction than you must simplify it. - Keller H.

4-6: Permutations of a Set
Notes: [|Section 4-6 Student 1011.pdf] media type="custom" key="7894689" View the lesson online Lesson on iTunes

You can find a permutation by taking out the important information of whatever you are trying to solve. Make sure you have the order right because in a permutation the order is very important, if you mess that up, you will be wrong. basically a permutation in arranging the information in a particular order. - Mitch H.

4-7: Combinations of a Set
Notes: [|Section 4-7 Student 1011.pdf] media type="custom" key="7916319" View the lesson online Lesson on iTunes

In this chapter it is saying how you can choose numbers with out the order mattering and to do that you use the formula nCr where you put n on the top then you put n minus r in // **Parentheses** // on the bottom and then r factorial to the right on the bottom and then solve it. - brandy
