Calculate the probability mass function of x
A probability mass function of a discrete random variable can be seen as a special case of two more general measure theoretic constructions: the distribution of and the probability density function of with respect to the counting measure. We make this more precise below. Suppose that is a probability space and that is a measurable space whose underlying σ-algebra is discrete, so in particular contains singleton sets of . In this setting, a random variable is discrete p… Web2 dagen geleden · Statistics and Probability; Statistics and Probability questions and answers; Let X be a random variable having the probability mass function …

WebThe probability mass function of X, denoted p, must satisfy the following: ∑ xi p(xi) = p(x1) + p(x2) + ⋯ = 1. p(xi) ≥ 0, for all xi. Furthermore, if A is a subset of the possible values of X, then the probability that X takes a value in A is given by. P(X ∈ A) = ∑ xi ∈ Ap(xi).
