Bookmark or Share- Power Set of a Power Empty Set - Mathematics Stack ExchangeIf you have a one-element set, the only possible subsets are those that contain the element or not, which is how you get P(P(∅)) P (P (∅)). For the next step, you now have just a two-element set, so you can have: 1. Neither element; 2. Element A; 3. Element B; 4.
- use contradiction to prove that the square root of $p$ is irrationalStack Exchange Network. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
- $L^p$ and $L^q$ space inclusion - Mathematics Stack ExchangeThe function dp: Lp(μ) × Lp(μ) → [0, ∞) given by dp(f, g) = (∫X | f − g | pdμ) min (1, 1 / p) = ‖f − g‖ min (p, 1) p defines a complete translation invariant metric on Lp(μ), and so, (Lp(μ), dp) is an F -space. (Of course when p ≥ 1, Lp(μ) is a Banach space with norm ‖f‖p = dp(0, f); for 0
- Poisson Distribution of sum of two random independent variablesYou can use Probability Generating Function(P.G.F). As poisson distribution is a discrete probability distribution, P.G.F. fits better in this case.For independent X and Y random variable which follows distribution Po($\lambda$) and Po($\mu$).
- probability theory - Why is $P(a < x < b) = P(a < x) - P(x < b ...First, you probably need to switch around the probabilities on the right. If a
