Definition 4.2 The joint probability mass function (pmf) of two discrete random variables \((X,Y)\) defined on a probability space with probability measure \(\textrm{P}\) is the function \(p_{X,Y}:\mathbb{R}^2\mapsto[0,1]\) defined by \[ p_{X,Y}(x,y) = \textrm{P}(X= x, Y= y) \qquad \text{ for all } x,y \]

E joint probability mass function

This would give us the marginal probability mass function. Once we have these marginal distributions, then we can analyze the two variables separately. Note: If X and Y are discrete, this distribution can be described with a joint probability mass function.

X2 and Y (a) We assign a joint probability mass function for X and Y as shown in the table below. and solve for a such that (1 − e−aα)(1 − e−aβ) The expected value (expectation) of a random variable X with p.m.f.
