4-1 is about experiments (an activity used to produce data that can be observed and recorded), relative frequency (compares the number of times the outcome occurs to the total number of observations), and experimental probability (which represents a likelihood of an event.) - Chelsey R.

**Student Summaries:** This section is about simulations, a model of a situation in which you carry out the trials, collect data and calculate probabilities. They can be done using coins, spinners, and number cubes. - Dani

**Student Summaries:** This section explained the probability formula and ways to find probabilities of events. It taught how to find all the possible outcomes for an event in an easy manner. This lesson talks about tree diagrams, sample spaces, events, the fundamental counting principle, and theoretical probability. ~Tabby L.

In this section it was about probability and the formula we used to find out the probability of an event. Showed that we can use the graphing calculator to help find out the prob by using spinners, dice etc. Also this section shows us to use tree diagrams and other types of theoretical probability. So this is what lesson 4-3 is all about.- Patrick E.

4-4: Probabilities of Compound Events

This lesson is about compound events, and mutually compound events. Compound events or made up of two or more simpler events. Mutually exclusive events cannot occur at the same time. To find the probability of mutually exclusive events you have to find the probability of all the events and then add them together. -Elayna V.B.
 * Student Summaries:**

section 4-4 was about probabilties of compound events which deals with more than one probabilites in one promblem. this might seem challenging to you, but if you follow these steps it wlll be easy. -Dylan K.

4-5: Independent and Dependent Events
Notes: [|Section 4-5 Student 1011.pdf] media type="custom" key="7883553" View the lesson online here Lesson on iTunes

This lesson is about finding the probability of independent and dependent events. If the result of one is event IS affected by the result of an another event then it is a dependent event. If the result does NOT have an effect by the result of the first event, then it is an independent event. These are actually used in life. (goverment, health, sports, games, family) -Elayna V.B.

4-6: Permutations of a Set
Notes: [|Section 4-6 Student 1011.pdf] media type="custom" key="7894691" View the lesson online Lesson on iTunes


 * Student Summaries:** A Permutation is an arrangement of item in a particular order. ORDER IS IMPORTANT!!!! A Factorial is the number of permutation of n items: nPr = n!/(n-r)! 4P2 = 4!/(4-2)! 4!/4-2 4!/2! (4)(3)(2)(1)/(2)(1) = 12 - Austin Z.

4-7: Combinations of a Set

**Student Summaries:** in this lesson we learned what a combination is and how to distinguish it from a permulation, and we also learned how to solve a combination using the formula for nCr= n!/(n-r)!r! -jimmy h.

u can distinguish the two by asking yourself if the order is important. If not, then your are dealing with a combination. If order indeed is important than you would use the equation listed above because it is a permutation. -dylan k.
