For example, a sigma algebra is a group of sets closed under a countable union.Īnother common example of the sigma (\) is that it is used to represent the standard deviation of the population or a probability distribution, where mu or μ represents the mean of the population). In General Mathematics, the lowercase letter (), is generally used to represent unknown angles, as well as, it is a prefix used in different situations to represent that a term is referred in some way to countable unions.
