This principle states that the total number of outcomes of two or more independent events is the product of the number of outcomes of each individual event. The fundamental counting principle or basic principle of counting is a method or a rule used to calculate the total number of outcomes when two or more events are occurring together. The fundamental rule can be used over a set of categories when one or more out of several choices in each of the categories is to have opted.Ī Deeper Understanding of the Fundamental Counting Principle This method of multiplication can be employed in solving the probability problems wherever there are different kinds of events taking place at the same time. Total number of unique ties = 5 x 3 x 4 = 60 So, in this case, the number of ties the person can stick with the available combinations is calculated using the Fundamental Principle of Counting definition as: However, it is not as easy as imagined for a larger number of outcomes for each event. So, 4 + 4 + 4 = 12 ties for red alone.) The traditional method may seem to be easy for smaller numbers. (Say for the color red, the person can make 4 designs of a tie for each shape. To find the number of unique ties he can make, it becomes a complex calculation if we are counting by the traditional method. Suppose he has a choice of 5 colors, 3 shapes, and 4 different design patterns.
He can make ties to be unique based on the following factors: color, shape, and design. In this particular article, we aim at making you learn one such important concept of Mathematics.ĭefinition Fundamental Principle of CountingĮxplanation of Fundamental Principle of Counting DefinitionĬonsider an example of a person who runs a business of sewing neckties. Students can either read the articles on a wide range of topics or can watch the video lectures on any topic. To make the learning more fun and engaging for the students, the subject experts at Vedantu have come up with unique study sessions where new concepts are being taught. The application of Mathematics is vast and touches every discipline in some or another way. Mathematics is an interesting subject, here every concept has a different technique and method of playing with numbers. The fundamental counting principle is one of the most important rules in Mathematics especially in probability problems and is used to find the number of ways in which the combination of several events can occur. That is when our Mathematicians came out with a way of determining large counts efficiently and accurately with the help of the fundamental counting principle.
However, they, later on, realized that these methods of counting cannot be used in cases where we are forced to count large and large quantities of numbers. Our ancestors first used fingers for counting and later started using beans, sticks, buttons, and beads to count. The whole world of Mathematics started with the basic necessity of counting. The term ‘counting’ is the fundamental concept of Mathematics.
