Web Quest Probability of compound events School Al

Web Quest: Probability of compound events School: Al Ahnaf Bin Qais Grade level: 8 Description: This quest is a part of probability unit, where student study theoretical and experimental probability, and compound events, beside solving daily life problems related to probability. Introduction vocabulary: sample space, theoretical probability, experimental probability, compound events Tasks Prepared by: Teacher / Mohammed Fathe Main page Process Evaluation Conclusion Teacher Page

Introduction: Probability occupy an important part of our daily life. We use probability in weather expectation of rain fall in nominated day, or expectation of a certain team to win a football match, or the kind of new born baby. Probability might be of simple experiment, such as tossing a coin, or compound such as rolling a dice, and spinning a spinner respectively. In this quest you will be a distinguished mathematician and will learn a lot about compound events, and their application in the daily life problems around you will solve problems based on daily life situations. Through your navigation, you will solve problems such as : school cafeteria sells two kinds of juice (mango and orange), and three types of sandwiches (cheese, tuna, and burger). What is the probability of one student buying mango and chees?

Tasks Teacher will divide students into groups of 3 to work on the given tasks. Students are expected to work together, and present their learning results as a product or paper work. Your objective of this web quest is to : 1 - give a definition of concepts such as (compound event and sample space) 2 - find the sample space of two compound experiments. 3 - calculate the probability of certain compound event. In this web quest you will use different files and web resources that will help you to achieve your web quest goals.

Process In groups, students will work on the following activities and present their finding using A 3 size paper. Students should share their findings with other groups. Task 1 (10 min. ) : Read the following file and. . * Define of the concepts: “compound event, sample space”. * Mention the methods that can be used to write the sample space of compound experiment. Task 2 (7 min. ) : watch the following video which shows different ways of representing the sample space of compound experiments. Task 3 (10 min. ) : use the following file to solve the problems related to compound experiment

Probability of compound events Definition of compound event, sample space, and tree diagram method of finding the sample space of two experiments

Process Use the knowledge you have gained through this web quest to solve the following problems on a separate sheet of paper: 1 Use the net method to determine the sample space of selecting the university and major area from the following two sets of universities, and majors A travel bag factory produces two kinds of bags one with locker and one without, and they produces the bags in three colores “black, brown, and blue”. Use tree diagram method to write the sample space of these two choices, and then find the probability of buying a blue bag without locker? ﻣﺎ ﺍﺣﺘﻤﺎﻝ ﺃﻦ ﻳﺸﺘﺮﻱ ﺷﺨﺺ ﺣﻘﻴﺒﺔ ﻣﻦ ﺍﻟﻤﺼﻨﻊ ﺯﺭﻗﺎﺀ ﻭﺑﺪﻭﻥ ﻗﻔﻞ 2 -

conclusion Dear Students: During this cognitive journey, you learned how to write the sample space of two composite events that resulted from two simple experiments. You learned the different ways of writing sample space, you solved daily life problems that included practical models of everyday life events and used compound events, also you have learned how to find the probability of a nominated compound event. You can increase your knowledge more by navigating the web and getting to know more about how to find the sample space for three compound events such as tossing a coin, a three-equal sector area colored spinner (red-yellow-green for instance), and a dice. What is the best method to represent the sample space and make it easy to find the probability of certain compound event?

Teachers’ page Dear colleagues: In this web quest, designed for grade 8 students who study statistics and probability unit, students learn definitions and how to find the sample space of two simple random experiments and identify the different methods of writing the compound events sample space, as well as solving problems related to what they have been learned related to their everyday life situation. This cognitive journey achieves the criteria of eighth grade math curriculum: 8. 8. 9 8. 8. 10 1. 1 Use problem conditions to calculate theoretical probabilities for possible outcomes. List systematically all the possible outcomes of an experiment. Represent and interpret problems and solutions in numeric, algebraic, geometric or graphical form, using correct terms and notation. Students read in this knowledge journey about complex events through a text file, and then watch an instructional video on how to write space in kind and how to find a probability of an event. They then work to solve life issues based on complex events. Students in this web quest read about compound events using text files, and videos , then solve problems related to what they have learned.
