SpletRecall: conditional probability distributions I It all starts with the de nition of conditional probability: P(AjB) = P(AB)=P(B). I If X and Y are jointly discrete random variables, we can use this to de ne a probability mass function for X given Y = y. I That is, we write p XjY (xjy) = PfX = xjY = yg= p(x;y) p Y (y) I In words: rst restrict sample space to pairs (x;y) with given

How can a PDF’s value be greater than 1 and its probability still integrate to 1? Even if the PDF f(x) takes on values greater than 1, if the domain that it integrates over is less than 1, it can add up to only 1.Let’s take an example of the easiest PDF — the uniform distribution defined on the domain [0, 0.5].The PDF of the uniform distribution is 1/(b-a), … hc resp vir rna 4 tgts sars cov2 https://theros.net
