Webb9 juni 2024 · Probability is a number between 0 and 1 that says how likely something is to occur: 0 means it’s impossible. 1 means it’s certain. The higher the probability of a value, the higher its frequency in a sample. More specifically, the probability of a value is its relative frequency in an infinitely large sample.

Webb13 aug. 2024 · 1 Answer. I think the best bet here is to use the Berry--Esseen inequality for the binomial distribution. Let X 1 := X, X 2 := Y, p 1 := p, q 1 := 1 − p 1, p 2 := q, q 2 := 1 − q 1, n 1 := n, n 2 := k. Let U 1 and U 2 be independent normal random variables (r.v.'s) with the first two moments matching those of X 1 and X 2, respectively. Webb30 juli 2024 · The probability density of one point ( x, y) is f X ( x) f Y ( y). You integrate the probability densities of all the points where x > y. You can do this in either integration order. Say you integrate d x d y, so the outer integral is the y integral. Now y can be anything, if x hasn't been picked yet, so the outer limits are − ∞ to ∞.
