Marginal density We define the marginal density for the variable $X$ as follows: \[\textrm{(D)}\quad\boxed{f_X(x_i)=\sum_{j}f_{XY}(x_i,y_j)}\quad\quad\textrm{and}\quad\textrm{(C)}\quad\boxed{f_X(x)=\int_{ …

Probability will be a rule given by the following Axioms (Laws that we all agree on) Let Sbe a sample space. A probability will be a function P(E) where the input is a set/event EˆSsuch that …
