Figure 4.3. The y -axis contains the probability of x, where X = the number of workers who have only a high school diploma. The number of adult workers that you expect to have a high school diploma but not pursue any further education is the mean, μ = np = (20) (0.41) = 8.2. The formula for the variance is σ 2 = npq.

· On a vu que, avec P(X) = Xp − X P ( X) = X p − X, modulo p p, on a : P(X + 1) = P(X) P ( X + 1) = P ( X). Ainsi sur Fp F p, le polynôme P(X) P ( X) ne prend qu'une seule valeur, par récurrence, car Fp ∼ Z/pZ F p ∼ Z / p Z est cyclique. Du coup cette valeur est P(0) = 0 P ( 0) = 0, et ∀a ∈ Fp ∀ a ∈ F p, on a : ap = a a p = a

The Binomial Distribution. If a discrete random variable X has the following probability density function (p.d.f.), it is said to have a binomial distribution: P (X = x) = n C x q (n-x) p x, where q = 1-p. p can be considered as the probability of a success, and q the probability of a failure. Note: n C r (“n choose r”) is more commonly

The HEX-P payload consists of a suite of three co-aligned X-ray telescopes designed to cover the 0.2 — 80 keV bandpass. The High Energy Telescope (HET) has an effective bandpass of 2-80 keV, and is composed of two High Energy Mirror Assemblies (HEMAs), which utilize thin electroformed Ni shells coated with Pt/C and W/Si multilayer coatings

: To find the expected value, E (X), or mean μ of a discrete random variable X, simply multiply each value of the random variable by its probability and add the products. The formula is given as E(X) = μ = ∑xP(x). E ( X) = μ = ∑ x P ( x). Here x represents values of the random variable X, P ( x) represents the corresponding probability
