离散型随机变量和连续型随机变量的期望,方差,矩的计算公式。 第四章 Probability distributions(概率分布) 大概占5%的分值。几种重要的离散型概率分布和连续型概率分布,它们的期望,方差在Formulae-and-Tables(俗称小黄书)里都可以找到。无需背诵这些公式,考试的时候直接查阅小黄书即可。提一下,这里有个很重要的性质:...
To prove that choose k out of n, replace and the order doesn't matter: P = (n+k-1,k) check the formula by an extreme and nontrivial example: n = 2 -17:08P = (k+1, k) = (k+1, 1) = k+1 Gorgeous proof, brilliant: 24:03Convert "choose k out of n" t...
The 19th century saw further advancements in probability, particularly with the work of Pierre-Simon Laplace. His work “Théorie analytique des probabilités” (Analytical Theory of Probability), published in 1812, brought together many ideas in probability and provided a comprehensive framework for u...
