Epistemic Configurations and Holistic Meaning of Binomial Distribution
Abstract
:1. Introduction
2. Theoretical Framework
- Problem situations: A problem field from which the object emerges, usually in an informal state that is formalized over time and generalized for application to similar situations.
- Processes: These correspond to the resolutive methods, such as algorithms and operations, associated with the resolution of the problem situation. These evolve over time, becoming refined and generating complementary or alternative approaches, such as demonstration or verification.
- Definitions-concepts: Descriptions with which the different probabilistic ideas are evoked. To each concept corresponds its definition, which may vary depending on the problem situation and in which a set of properties is presented.
- Properties-propositions. Properties correspond to the attributes possessed by the mentioned objects, expressed by means of propositions which allow linking or associating them with others. For example, the multiplicative principles of probability allow linking probability with calculus.
- Arguments: Statements used to validate refutable objects (propositions and procedures). In current mathematics, deductive arguments predominate. However, those of antiquity, with which the first problematic situations were modeled, were mostly inductive or recursive.
- Linguistic elements: These correspond to the terms, expressions, notations, graphs, and tables evidenced in different registers through which data, solutions, and ideas are expressed and represented. Vásquez and Alsina [2] point out the following essential linguistic elements for probability: common language, probabilistic language, representation in tables and graphs, numerical representation, and the tree diagram. In the answers studied in our work, to facilitate their analysis, we will consider the categories of common (words), symbolic (purely mathematical expressions, such as equations), tabular, and graphical language.

Problem Situation | S1. Study the cases that a binomial phenomenon can give. S1.1 In how many and what ways can two things be selected from “X” different things? Example: How many ways can two things be selected from 5 different things? S1.2 How many or which cases (favorable and unfavorable) do I have when throwing a die or flipping a coin if I want a specific amount of successes? Examples: What are the possible cases in throwing 2 or 3 dice? What are the favorable cases in flipping 2 coins if I want one side? |
Definitions-Concepts | Chance, case, event (both excluding and non-excluding events), numerical pattern, power, inequality, unknown, binomial coefficient, combinatorial, variable value, order, permutation, variation, probability in the form of ratios, figured numbers, Pascal’s triangle, repetition, sample space, discrete random variable, and factorial. |
Processes | Exploration and modeling Direct counting of cases, exploration of possible outcomes (construction of the sample space), pattern recognition and construction as well as validation of algorithms based on them, search for properties, and use of representations such as tree diagrams. |
Properties-Propositions | Linking mathematics with the uncertainty of chance Games of chance, as well as other phenomena, follow a behavior that allows them to be analyzed among different representations. A degree of knowledge of chance can be obtained by using mathematical expressions. Adding the possible cases of two or more events gives the number of total arrangements (additive principle for counting cases). Multiplying the possible cases of two or more events gives the number of total arrangements (multiplicative principle for counting cases). |
Arguments | Inductive and recursive principles for constructing expressions and discovering properties. Use of representations. |
Language | Unrefined mathematically and probabilistically (arithmetic expressions), focused on case counting. Tabular and graphical. |

S2.5 What is the probability of getting at least “X” hits in “n” throws (defined probability) or another interval of the probability distribution? Example: What is the probability of getting at least 1 head in a toss of 3 coins? S2.6 Study the expectation of A (against B) if a series of trials stops, where A needs “a” successful trials and B needs “b” successful trials (with equal probability). Example: Considering that both players have an equal probability of winning, what is the hope of player A if he or she must win 3 times against player B, who wins by winning 2 times? |
Definitions-Concepts | Probability as a numerical value between 0 and 1, the value associated with a random experiment, probability distribution, summation, and the extension of binomial development. |
Processes | Modeling probabilistic phenomenon Identify characteristics of probabilistic phenomena. Generation, verification, or correction of mathematical models of phenomena of a binomial nature from the definitions and concepts mentioned above. Calculation of the expected value when assigning values to the probabilities of a phenomenon. |
Properties-Propositions | Linking probability with mathematics The expected value of a binomial experiment corresponds to the summation of the products of the value of each variable by its respective probability of occurrence. We can obtain the probabilities associated with a binomial phenomenon by studying the expansion expression “(p + q)n”, in which “p” and “q” are their probabilities and “n” is the number of repetitions of the trials. The additive and multiplicative principles of probability. |
Arguments | Deductive. Inductive. Use of representations. |
Language | Common, symbolic, tabular, and graphical language that relates the definitions and concepts of meanings 1 and 2 to the calculation of specific probabilities. |

Problem-Situation | S.3 Study probability in binomial variable situations. S3.1 What is the probability of having “m” successes in “n” attempts (using the formula)? Example: What is the probability of getting “k” successes in 30 trials with p = 0.6? S3.2 What is the expectation (expected value) of a binomial variable phenomenon? Example: What is the expected outcome of a toss of 20 coins? S.3.3 What is the most probable value of the random variable number of successes? Example: What is the most probable number of heads when tossing 40 coins? S.3.4 What is the degree of dispersion of the number of successes obtained in a binomial phenomenon? Example: How dispersed are the results of 5 binomial trials with p = 3/4? S3.5 Probability of obtaining at least “X” hits in “n” trials (indefinite or variable probability) or another interval of the probability distribution. Example: What is the probability of getting at least 20 heads in a series of coin tosses? S3.6 Let “x” be the number of successes and “y” be the number of failures (x + y = n), and let A win if x ≥ m. What is the expectation that B wins? Example: Considering that both players have different probabilities of winning, what is the hope of player A if he or she has to win 3 times versus player B, who wins by winning 2 times?S.3.7 How many trials are necessary to have at least “c” successes? Example: After how many binomial trials with p = 7/8 can one be sure that there is at least one failure? |
Definitions-concepts | Binomial distribution, binomial distribution formula, probability function, parameter, probabilistic inference, degree of knowledge (subjective probability), mean, variance, and expected value (hope). |
Processes | Application for analysis Determination of parameters of the binomial distribution. Calculate the probability by directly applying the formula. Compare theoretical values of a binomial phenomenon and observed ratios. Varying parameters in simulations. Approximating or calculating measures such as mean and variance. |
Properties-Propositions | Link the mathematical binomial distribution with the rest of mathematics and probability. In a binomial phenomenon, there are “n” observations. The observations or trials in a binomial phenomenon are independent. In a binomial phenomenon, there are only 2 outcomes (success and failure). The probabilities of success and failure are constant. In a binomial trial, the probability of getting “m” hits in “n” trials with a probability of success “p” is given by the binomial formula. The expected value in a binomial phenomenon is given by its mean. Considering a high series of experiments, if the observed proportion does not agree with the theoretical probability, we can assume that the phenomenon is not binomial. |
Arguments | Deductive. Use of representations. |
Language | The use of symbolic language is predominant, while the use of tables and graphs is used to study particular cases. |
