Conditional marginal and joint probabilities

WebApr 12, 2024 · Joint probability distributions are used to describe the probabilities of two or more random variables taking particular values. Therefore, both marginal and conditional distributions depend on the joint probability distribution of the variables being observed. Third, both marginal and conditional distributions sum to 1. WebConditional Probability. Conditional probability works much like the discrete case. For random vari-ables X;Y with joint pdf f(x;y) and marginal pdf’s f X(x) and f Y(y), we define the conditional density function: f(xjY = y) = (f(x;y) f Y(y) for all values of ywhere f Y(y) 6= 0 0 otherwise Now, conditional probabilities are found by ...
