👉 In probability theory and statistics, a microsomial is a type of random variable that can take values only in finite discrete subsets of its domain. Specifically, it refers to a random variable whose possible values are restricted to a set of a certain size (often 2 or 3 for typical applications) and which has a fixed distribution. In other words, a microsomial is a type of probability distribution that can be characterized by only being defined on a finite number of discrete outcomes. This means
