2022年4月28日 · 特别地, 0-1分布即为B (1, p). 【0-1分布就是进行一次伯努利实验】 注意:二项分布理论上 只适用于有放回抽样, 但当 n很大时, 也可近似用于无放回抽样. 因为要是没有放回,就会改变整体的概率了。 如果量很大的时候,拿走一个并不会对概率有多大的变化,所以可以近似。 证明:二项分布的分布律为. P\ {X=k\}=\mathrm {C}_ {n}^ {k} p^ {k} q^ {n-k} \quad (k=0,1,2, \cdots, n, p+q=1) 由公式 k \cdot \mathrm {C}_ {n}^ {k}=n \cdot \mathrm {C}_ {n-1}^ {k-1} 有.

Binomial distribution - Wikipedia
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean -valued outcome: success (with probability p) or failure (with probability q = 1 − p).

Permutation and Combination Calculator
Permutations and combinations are part of a branch of mathematics called combinatorics, which involves studying finite, discrete structures. Permutations are specific selections of elements within a set where the order in which the elements are arranged is important, while combinations involve the selection of elements without regard for order.

概率统计 B 第二章随机变量与概率分布
设0 < p < 1,设随机变量X 只能取1,0,其分布为 P(X = 1) =p P(X = 0) =1−p 称X 服从两点分布,p 称为其分布参数。也叫做伯努利分布 (Bernoulli)。可记作b(1,p) 分布。 根据李东风老师课件修改() 概率统计B 第二章随机变量与概率分布 2017 春季学期 13 / 75. . . ....
关于P (AB)的公式? - 知乎
若事件A和事件B不相互独立,应用条件概率公式求P(AB),即 P(AB)=P(A|B)\\cdot P(B) 。 例,如投掷一枚色子,则样本空间 \\Omega=\\{\\omega_1,\\omega_2,\\omega_3,\\omega_4,\\omega_5,\\omega_6\\} ,令A=掷出偶数= \\{\\omega_2,\\omega_4,\\omega_6\\} ,B=掷出素数= \\{\\omega_2,\\omega_3,\\omega_5,\\} 。
