How to solve joint probability
WebThen we will find the cumulative distribution function (CDF) for T and differentiate it to obtain the probability density function (PDF) for T. After that, we can solve each part of … WebTo summarize, if we know the joint probability distribution over an arbi-trary set of random variables fX1:::X ng, then we can calculate the conditional and joint probability distributions for arbitrary subsets of these variables (e.g., P(X njX1:::X n 1)). In theory, we can in this way solve any classification, re-
