Splet28. maj 2015 · 在这里，p（AB）=p（A）p（B）成立，所以20岁和女生才是独立的。 AB独立并不是指A和B这两件事无关，而是指两个概率不相互影响。比如我抛硬币的时候有风，可能会把原来正面吹成反面，也可能把反面吹成正面，这两件事有关，但是只要概率不互相影 … SpletP(A B)=P(AB)/P(B) by definition, P(A)=P(AB)/P(B) if A and B are independent, hence P(A)P(B)=P(AB); this is sometimes given as the definition of independence. Rearranging this last equation as P(AB)/P(A)=P(B), we see that if P(A B)=P(A), then also P(B A)=P(B). Examples: If P(A)=.5, P(B)=.4, and P(AB)=.2, then P(A B)=.2/.4=.5 = P(A) and SpletArguing from the intuitive idea of probability (be it frequentist, Bayesian, or a la Jaynes), what can we say about P(AB)?

Splet结合上图来理解。原来样本空间是 Ω，事件b发生，意味着样本空间缩小到b的范围，即上图黄色椭圆范围内。同时事件a也发生，也就是上图中 a∩b 蓝色部分，蓝色部分对黄色椭圆的占比，就是条件概率 p(a b)。 thierry catteau tahitiSpletP (A∩B) = Probability of happening of both A and B. From these two formulas, we can derive the product formulas of probability.
