(a) What is the probability of a Type I error? Webb30 jan. 2024 · In fact, we can calculate the PMFs of X and Y by using the formulas pX (x) = y∑ pX,Y (x,y), pY (y) = x∑ pX,Y (x,y) We sometimes refer to pX and pY as the marginal PMFs (边缘分布列), to distinguish them from the joint PMF. Problem 26. PMF of the minimum of several random variables.

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).
