Or means that the outcome has to satisfy one condition, or the other condition, or both at the same time. Two events are mutually exclusive if they cannot occur at the same time. Another word that means mutually exclusive is disjoint. If two events are disjoint, then the probability of them both occurring at the same time is 0. Understanding the difference between a prediction and the probability of a particular outcome occurring is an important distinction for successful investors.
Predictions are absolute, right or wrong. Probabilities run a spectrum, from highly unlikely to extremely likely. Furthermore, probability is not predictability. Too often are we over confident because probabilities make unlikely events seem impossible, when in fact they are extremely possible. Well, it has to do with how the probability is calculated and what the outcomes mean. Well, a predicted probability is, essentially, in its most basic form, the probability of an event that is calculated from available data.
Probability provides information about the likelihood that something will happen. Meteorologists, for instance, use weather patterns to predict the probability of rain. In epidemiology, probability theory is used to understand the relationship between exposures and the risk of health effects.
A probability of 1 means that the event will happen. If the probability of a road traffic accident was 1 there would be nothing you could do to stop it. It will happen.
In practice probabilities associated with everyday life events lie somewhere between 0 and 1. Converting between odds and probability is straightforward: To convert from a probability to odds, divide the probability by one minus that probability.
To convert from odds to a probability, divide the odds by one plus the odds. Objectives Upon completion of this lesson, students will: have seen that knowledge of probability concepts is useful when looking at sports have learned to search for a specific topic on the internet. Grade 6 Statistics and Probability The student demonstrates a conceptual understanding of probability and counting techniques.
Grade 7 Statistics and Probability The student demonstrates a conceptual understanding of probability and counting techniques. Grade 8 Statistics and Probability The student demonstrates a conceptual understanding of probability and counting techniques. Grade 9 Statistics and Probability The student demonstrates a conceptual understanding of probability and counting techniques.
Seventh Grade Statistics and Probability Investigate chance processes and develop, use, and evaluate probability models. Statistics and Probability Using Probability to Make Decisions Calculate expected values and use them to solve problems Use probability to evaluate outcomes of decisions Third Grade Measurement and Data Represent and interpret data. Grades Data Analysis and Probability Develop and evaluate inferences and predictions that are based on data Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them Understand and apply basic concepts of probability.
Advanced Functions and Modeling Data Analysis and Probability Competency Goal 1: The learner will analyze data and apply probability concepts to solve problems. Students then use real data to research specific topics in the sport where probability is relevant. The student does internet research on a sport to begin. This idea should appeal to most students and provide good real world applications for probability.
Student Prerequisites Arithmetic: Student must be able to: relate the sports information they collect to mathematical expression use simple addition, subtraction, multiplication and division when working with the sports information they collect Technological: Students must be able to: perform basic mouse manipulations such as point, click and drag use a browser for experimenting with the activities. Teacher Preparation Access to a browser Pencil and Paper.
Key Terms experimental probability The chances of something happening, based on repeated testing and observing results. It is the ratio of the number of times an event occurred to the number of times tested. For example, to find the experimental probability of winning a game, one must play the game many times, then divide the number of games won by the total number of games played probability The measure of how likely it is for an event to occur.
The meaning interpretation of probability is the subject of theories of probability. However, any rule for assigning probabilities to events has to satisfy the axioms of probability theoretical probability The chances of events happening as determined by calculating results that would occur under ideal circumstances. Contrast with experimental probability. Say something like this: Today, class, we are going to learn how probability applies to sports.
Alternate Outline This lesson can be rearranged in several ways. Suggested Follow-Up After this lesson, the students will have seen practical applications of how probability is used in everyday situations such as sports. Probability and sports Abstract This lesson is devoted to Internet research on a specific topic: finding topics in sports where probability is relevant.
Alternate Outlines This lesson can be rearranged in several ways. For practice using internet search engines, students, individually or in groups, can read the discussion about Internet Search and Set Operations. For an introduction to the difference between probability and statistics, students can read the Probability vs. Statistics discussion. Suggested Follow-Up After this lesson, the students will have seen practical applications of how probability is used in everyday situations such as sports.
The next lesson, Ideas That Lead to Probability , introduces ideas that are the basis of probability theory. By using everyday experiences and intuitive understanding, this lesson gives students a gradual introduction to probability.
Students will work with random number generators learn what it means for a game to be fair.
