Your homework is to learn about the skills, the classwork will be the practice part. = = = = Take out a piece of paper and write __//Probability//__ at the top. Watch the videos for Lesson 1 and 2. Stop the videos to allow for time to take notes and practice as you watch (just like you would do in class). Write down any questions you want us to review in class and put your questions in the Homework book first thing in the morning. If there are no questions, we'll know you're ready to apply the skills, and move on to the next lesson. = = = = =


 * Lesson 1: Impossible, Not Likely, Possible or Likely, Certain**

Key Terms (Learn these terms) An **experiment** **is a situation involving chance or probability that leads to results called outcomes.** An **outcome** **is the result of a single trial of an experiment.** An **event** **is one or more outcomes of an experiment.**
 * Probability ** is the measure of how likely an event is.


 * Lesson 2: find the __//probability//__ of an event, and understand the __//complement//__ of an event.**

This is how you write the probaility of an event: __The Number Of Ways Event A Can Occur__ P(A) = The total number Of Possible Outcomes

= Probability Lesson: Tuesday, Jan. 25th = = = = Let's continue with our flipped lesson. Remember: your homework is to learn about the skills and the classwork will be the practice part. = = = = Take out a piece of paper and write __//Probability of an Event//__ at the top. Watch the video for Lesson 3. Stop the video to allow for time to take notes and practice as you watch (just like you would do in class). Write down any questions you want to review in class. Place your questions in the Homework book first thing in the morning. If there are no questions, that means you're ready to apply the skills and move on to the next lesson. = = = = = Lesson 3: find the __//probability//__ of an event, and understand the __//complement//__ of an event.

===Find the probability of this problem:=== A spinner has 4 equal sectors colored yellow, blue, green and red. After spinning the spinner, what is the probability of landing on each color? Outcomes:The possible outcomes of this experiment are yellow, ___,__ __, and__. P(yellow) = __# of ways to land on yellow__ P(blue) = __# of ways to land on blue__ P(green) = __# of ways to land on green__ P(red) = __# of ways to land on red__ total # of colors total # of colors total # of colors total # of colors
 * The probability of event A is the number of ways event A can occur divided by the total number of possible outcomes. Let's take a look at a slight modification of the problem from the top of the page. ||

=== **Find the probability of these problem:** === 1. A glass jar contains 6 red, 5 green, 8 blue and 3 yellow marbles. If a single marble is chosen at random from the jar, what is the probability of choosing a red marble? a green marble? a blue marble? a yellow marble?

2. Choose a number at random from 1 to 5. What is the probability the number chosen is 4? What is the probability that the number chosen is even? What is the probability that the number chosen is odd?

1. P(red) = 6/22 = 3/11; P(green) = 5/22; P(blue) = 8/22 = 4/11; P(yellow) = 3/22 2. P(4) = 1/5; P(even) = 2/5; P(odd) = 3/5
