4-1: Experiments and Probabilities
Notes: [|Section 4-1 Student 0910.pdf] media type="custom" key="5720523" View a lesson summary here Summary on iTunes

We defined experiment and experimental probabilities, experiment is an activity used to produce data that is observed and recorded. Experimental probability is when the likelihood an event is going to occur, we also defined relative frequency, which is comparing the number of times an outcome occurs to the total number of observation. Experimental probability equation is P(E) equals number of observations favorable to E over total number of observations. You can use different ways to figure out an experiment such as flipping a coin, a spinner, or use a deck of cards, or a dice. - Andrew E. & Adam B.
 * Student Summaries:** In lesson 4-1 we learned about experiments and probabilities. We learned how to collect data with experiments and to use data to find experimental probabilities.

4-2: Problem Solving Skills: Simulations
Notes: [|Section 4-2 Student 0910.pdf] media type="custom" key="5732601" View a lesson summary here Summary on iTunes

In this lesson we learned how simulations are used to relate probabilities. Key words to know are Act it Out and Simulation. Act It Out is going through all of the motions of an experiment. Simulation is a model of a situation where trials are carried out using a simple experiment to represent something more complex. There are apps on our calculators that help us simulate the probabilities. -Rachel K. To find out the probability you need to go through all the motions of the experiment or Act It Out. You can use a Simulation which is a model where trials are carried out. There is an app on our calculators that helps us. There are many ways to conduct the experiment, but the most common ones are...a coin, dice, spinner, or a deck of cards. -Hannah B.

4-3: Sample Spaces and Theoretical Probability
Notes: [|Section 4-3 Student 0910.pdf] media type="custom" key="5802187" View a lesson summary here Summary on iTunes

This lesson was called Sample Spaces and Theoretical Probability. The formula we use for finding theoretical probability along with the counting principle is P(E)= Favorable/ Total. We also learned that we can use a tree diagram to count the total number of combinations or the possible outcomes. What you do for the tree diagram is you take all the options of the first thing then branch off all the objects of the second thing from it and so on until you run out of objects. Then when your done you count the number of outcomes for your total. If the problem is to large for the tree diagram you can use the fundamental counting principle. What you do for that is multiply the number of possible outcomes for each stage. -Rachel K. & Trevor S.

4-4: Probability of Compound Events
Notes: [|Section 4-4 Student 0910.pdf] media type="custom" key="5810157" View a lesson summary here Summary on iTunes Chapter 4 lesson 4 is dealing with probability of compound events. sample space is all the possible answers. Compound event is an event made up of two or more events. An example is when your roll two dice or pulling two cards out of a regular deck of playing cards. You would take what you rolled or picked and put that over a the whole and then do your next pick and over the whole and add the two fractions together to get the percentage or probability. -Jordan J. and Jake E.

4-5: Independent and Dependent Events
Notes: [|Section 4-5 Student 0910.pdf] media type="custom" key="5864141" View a lesson summary here Summary on iTunes

In this section we learned about independent and dependent events. Independent is when the second event is NOT affected by the result of the first event. Dependent is when the second even IS affected by the result of the first event. If it is a independent one, the number on the bottom will stay the same. If it is independent the number will go down one every time you run through the event again. -Hannah B. and Davin H.
