WebbThe 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). Webb17 feb. 2024 · The formula for a standard probability distribution is as expressed: P (x) = (1/√2πσ²)e − (x − μ)²/2σ² Where, μ = Mean σ = Standard Distribution. x = Normal random variable. Note: If mean (μ) = 0 and standard deviation (σ) = 1, then this distribution is described to be normal distribution. Binomial Probability Distribution Formula
