pls dont plagirize giving all my points for this assignment plz put in your own words 1. When can you use a circle graph instead of a bar graph to display data? 2. If a section in a circle graph is formed by a right angle, what percent of the total is represented by that section? Drawing Circle Graphs 1. When you are making a circle graph by hand, how do you convert a number for a part into its corresponding angle measure in the circle graph? 2. When you are making a circle graph by hand, what should you do if one of your angle measures is greater than 180°? Lesson: Probability Basics How Likely Is It? 1. In your own words, what is probability? 2. Draw a number line from 0 to 1 to represent the probability of an event. Place the words likely, unlikely, certain, impossible, and equally likely on your diagram. Represent a Probability 1. In probability, what is an outcome and what is an event? 2. What does the first number in a probability ratio represent? 3. What does the second number in a probability ratio represent? Make a Spinner 1. How can you set up a spinner so that an event is likely? 2. How can you set up a spinner so that an event is unlikely? 3. How can you set up a spinner so that an event is impossible? 4. How can you set up a spinner so that an event is certain? Lesson: Counting Venn Diagrams 1. What does a dot in the overlapping region represent? 2. What does a dot represent if it is in a circle but not in the overlapping region? 3. What does a dot that is outside of both circles represent? Tree Diagrams 1. For what type of situation is a tree diagram a suitable way to organize information? 2. Explain how to read a tree diagram to determine the possible outcomes for that situation. Lesson: Probability and Experiments Finding Probability 1. What does the notation P(event) represent? 2. Write the ratio that you can use to find P(event). 3. In the ratio for P(event), is it possible for the numerator to be greater than the denominator? Explain. Conducting an Experiment 1. What are the possible outcomes for tossing a coin? 2. What is the probability of getting heads when tossing a coin? 3. When tossing a coin several times, will you get heads on exactly 50% of the tosses? Explain why or why not. Lesson: Experimental Probability Finding Experimental Probability 1. What is the formula for experimental probability? 2. What is a trial? Lesson: Theoretical Probability Using Theoretical Probability 1. How does a theoretical probability differ from an experimental probability? 2. How can you use theoretical probability to make a prediction? Lesson: The Law of Large Numbers Theoretical vs. Experimental 1. Which type of probability is based on the way the experiment is designed? 2. Which type of probability is based on results? Closer and Closer State the law of large numbers in your own words.

Tell why they are dependent. Probability of Independent Events 1. How do you find P(A and B) if A and B are independent events for two or more actions, such as tossing a coin twice and finding P(heads and heads)? 2. How do you find P(A or B) if A and B are independent events for one action, such as spinning a four-color spinner once and finding P(red or blue)? Lesson: Dependent Event Probability Probability of Dependent Events 1. How do you find P(A and B) if A and B are dependent events for two or more actions, such as selecting two candies and drawing P(green, and then pink)? Lesson: Complementary Events Complementary Events 1. Give an example of complementary events. Explain why they are complementary. 2. Why is the sum of the probabilities of complementary events always equal to 1? Nonoverlapping Events 1. If events A and B are non-overlapping events, how do you find the probability that one or the other occurs? 2. What does it mean if P(A or B) equals 1?

1. A circle graph may be used when there is some meaning to the
total of the observations. It may be a sensible option when there
are at most seven sectors, none of which are too small.

The Graph Should Be in proper progression and Should Be neat and Good scaled.
Hope it helps you dear.......xD
