Webt. e. In probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. [1] [2] It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events ( subsets of the sample space). WebFeb 17, 2024 · A discrete variable is a variable that takes on distinct, countable values. In theory, you should always be able to count the values of a discrete variable. Examples Examples of discrete variables include: Years of schooling Number of goals made in a soccer match Number of red M&M’s in a candy jar Votes for a particular politician
WebSpecifically, we can compute the probability that a discrete random variable equals a specific value ( probability mass function) and the probability that a random variable is less than or equal to a specific value ( cumulative distribution function ). Probability Mass Functions (PMFs)
WebA discrete random variable can be defined as a type of variable whose value depends upon the numerical outcomes of a certain random phenomenon. It is also known as a stochastic variable.
