It has been on the theory of probability is sporting at least more than three hundred years. Since the discovery by Fermat and Pascal Pascal and Fermat in the seventeenth century has become an integral part of our daily lives. At one time or another have made each and every one of us to take chances through decisions , throw the dice , or pull the cards. Often made based on the provisions of the possibility or probability that a certain event will happen. Developments in the theory and simple applications to a range of potential activities are as important as the physical sciences and genetics, social sciences and economics , industry and engineering and insurance. Because of its use on a large scale, should be to provide the application of probability theory in mathematics in high school. In this unit of the curriculum will try to improve students ' understanding of the ideas included in the initial theory of probability . It will clearly define the unit important words and ideas. The formulas will solve the problems . The relays will be discussed Permutations, and combinations , and the Probability . Applications will appear theory to practical problems in the unit. After explaining each subject is given a set of practices . There are many of the basic objectives of this chapter of the book. Upon completion of the unit, the student will be able to : - Understand and appreciate the Probability use in everyday life. - Solve problems involving the Permutations, and combinations . - The definition of key terms used in mathematical probability . - Calculate the probability of the occurrence of a specific event that will happen.
